The PT1B(/M) translation stage is configured with a 1/4"-170 TPI adjuster, which has a 1.00" (25.4 mm) travel range. The adjuster can either be actuated by hand or by the 5/64" (2.0 mm) hex located on the end. Each stage includes two alignment dowel pins and contains sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep. Two oversized 1/4" (M6) counterbores allow the stage to be directly attached to a mounting adapter (sold below) or a metric or imperial breadboard with user-supplied cap screws.

These linear translation stages feature crossed-roller bearing travel mechanisms for precision motion, high load capacity, and low angular deviation. The LNR Series stages feature all-steel body construction, while the LX, XRN, and XR Series stage bodies are constructed of cast tool and jig aluminum. We also offer several vertical crossed-roller bearing stages (see below).

Screw the PT102(/M) Angle Bracket to the PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes on the front face of the angle brakcet for aligning the third and final stage.

XYZ AssemblyThe modular design of the PT series translation stages allows the assembly of 2- or 3-axis stages within minutes. Each stage comes with two precision dowel pins that allow for right- or left-handed XY configurations with excellent orthogonality. Follow the steps in the animation to the left or the photos below to build a 3-axis XYZ translator (PT3) from individual components.

Stereo microscopes are designed for low magnification observations and use two separate optical paths to create a 3D image of the specimen. The two types of lenses used in stereo microscopes are zoom lenses and fixed lenses.

By understanding the different microscope lens types and their applications, you can select the best microscope lens for your specific needs and achieve the best possible results.

Thorlabs' Nanoflex™ translation stages feature frictionless flexure mechanisms for improved positioning and resolution when compared to similar stages made using bearings. The translation of the stage is accomplished by the elastic deformation (flexing) of a linkage attached to the mounting platform. Most models also include piezo actuators for small position adjustments.

Custom OptionsAny PT series translation stage can be purchased as a special order without a micrometer, thereby allowing the user to choose from our large selection of manual and motorized actuators. We also offer screw adjusters that have Ø3/8" barrel adapters for 1/4"-80, 1/4"-100, or M6 x 0.25 threads, making them compatible with the stages below. Please see the selection guide in the Actuators tab for a list of compatible actuators. Please contact Tech Support to discuss the various micrometer options and to get quotes for custom configurations with or without alternative actuator options.

If the fine adjustment knob on the DM12 is accidentally removed, it can reattached. Please refer to our DM12 Knob Attachment tab on our DM12 differential drive page for details.

The eyepiece lens, also known as the ocular lens, is located at the top of the microscope and is the lens through which the viewer observes the specimen. Eyepiece lenses are usually 10x magnification and can be swapped out to change the overall magnification of the microscope.

The PT3(/M) XYZ configured stages include both the PT101(/M) and PT102(/M) adapters. Please see the XYZ Assembly tab for more information on using these adapters to create a multi-axis configuration.

These compact stages incorporate dovetails and a leadscrew for the translation mechanism. They are suitable in general purpose motion control applications.

A CCD (Charge-Coupled Device) sensor is an image sensor that uses a complex manufacturing process to create an image. They are more expensive than CMOS sensors but offer better image quality and sensitivity.

In summary, compound microscope lenses include the eyepiece lens and objective lens, stereo microscope lenses include zoom and fixed lenses, digital microscope lenses include CMOS and CCD sensors, and polarizing microscope lenses include the polarizer lens and analyzer lens.

Telecentric zoom lens allows the user to change the magnification of the microscope continuously. They are convenient for studying specimens with varying sizes and structures.

Types ofobjectivelenses

The objective lens is located on the nosepiece, which is the rotating turret that holds the objective lenses. Objective lenses come in different magnifications, ranging from 4x to 100x or higher, and can be swapped out to change the magnification of the microscope. The objective lens is the primary lens that determines the resolution and quality of the image.

Using the DM713 alone creates an extra step where the user has to read and record the display, which can be tedious in a dark lab where the display is not visible. One solution is to use Thorlabs' SBC-COMM, which includes an RS-232 interfacing cable. Thorlabs has created software application notes that walk the user through creating Visual C#® and LabVIEW® programs to continuously measure distances with the DM713. The application notes can be downloaded from links in the following section.

Digital micrometers, such as the DM713, are handy for moving a piece of optomech a specific distance. For example, a user might want to increment a translation stage holding a sample in front of an objective lens in order to focus the light to equally spaced points within the sample.

Thorlabs' PT Translation Stages have a 1.00" (25.0 mm) translation range and feature hardened steel linear bearings for precise motion and long life. These translation stages are available preconfigured with an adjuster screw, standard manual micrometer, or differential adjuster. The actuator on the translation stage can be removed by loosening the screw on the barrel clamp with a 3/32" (2.5 mm) hex key.

The analyzer lens is located above the objective lens and helps to eliminate glare and unwanted reflections. By adjusting the orientation of the analyzer lens, the viewer can observe how the specimen interacts with polarized light.

Another solution is to purchase the Mitutoyo® 05CZA662 SPC cable and IT-016U USB input tool that provide a push button and USB interfacing cable. With this device the user can open any text entry software package, press the single push button, and the device acts like a keyboard to enter the number into the software.

However, there are also times where the user might want to record the position of an event. One example could be making a distance measurement where the micrometer is set to a starting position, zeroed, and then translated the desired amount to display the distance.

The differential adjustment knob provides 25 µm of translation per revolution over a 250 µm range and features graduations every 0.5 µm. Two oversized 1/4" (M6) counterbores allow the stage to be directly attached to a mounting adapter (sold below) or a metric or imperial breadboard with user-supplied cap screws. Each stage includes two alignment dowel pins and contains sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep.

The PT Series translation stages can be purchased individually (PT1 Series) or as fully assembled, 3-axis, XYZ translators (PT3 Series). Therefore, the PT3A stage can be disassembled using a 3/16" (5 mm) hex key to customize the positions of the micrometers or to use three PT1 stages separately, see the XYZ Assembly tab for details.

A microscope lens is a critical component of a microscope. It is responsible for magnifying the image and resolving details of the specimen being examined. Microscope lenses come in different types, each with its own unique characteristics and applications. In this article, we will delve into the different microscope lens types and their functions.

The PT3A(/M) translation stage is offered with differential micrometers for applications requiring increased resolution. The coarse adjustment, which can be locked using a thumbscrew on the mounting collar, provides 0.5 mm of translation per revolution over a range of 1" (25.4 mm).

Insert the two 1/8" alignment pins into the PT101(/M) Base and then screw it onto a PT series translation stage using the two included 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes to ensure orthogonality of the second stage.

Polarizing microscopes are used to study the properties of materials that interact with polarized light. The two types of lenses used in polarizing microscopes are the polarizer lens and the analyzer lens.

The PT1(/M) translation stage is configured with the 150-811ST micrometer drive, which has a 1.00" travel range and engraved graduations every 0.001". The PT1/M is fitted with the metric 150-801ME micrometer, which has a 25.0 mm travel range and engraved graduations every 10 µm. Each stage includes two alignment dowel pins and contains sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep. Two oversized 1/4" (M6) counterbores allow the stage to be directly attached to a mounting adapter (sold below) or a metric or imperial breadboard with user-supplied cap screws.

The polarizer lens is located beneath the stage of the microscope and polarizes the light that passes through the specimen.

The actuators above are compatible with all of the stages offered on this page, with the exception of PT1/M and PT3/M stages sold before December 30, 2015. Please refer to the footnotes above for more information.

Compound microscopes are the most common type of microscope and use two lenses to magnify the image: the eyepiece lens and the objective lens.

The PT3(/M) translation stage is fitted with standard 1" 150-811ST micrometer drives, each of which is engraved every 0.001", while its metric counterpart (PT3/M) comes with 150-801ME micrometers, which offer 25 mm of travel and are engraved every 10 µm. Each stage offers sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep.

If the fine adjustment knob on the DM12 is accidentally removed, it can be reattached. Please refer to the DM12 Knob Attachment tab on our DM12 differential drive page for details.

Thorlabs' manual translation stages are offered in a range of maximum travel distances, from less than 1/4" (6 mm) to 2" (50 mm) and longer for our long travel, large area platforms. Many of these stages can be ordered in multi-axis configurations, providing XY or XYZ translation. For fiber coupling applications, please see our Multi-Axis Stages, which offer finer adjustment than our standard manual translation stages. In addition to linear translation stages, we offer rotation stages, pitch and yaw platforms, and goniometers. We also offer motorized translation stages that are powered by DC Servo motors, stepper motors, or direct drive technology.

Whatare the 3objectivelenseson a microscope

The PT102(/M) is an angle bracket with four 1/4"-20 (M6) mounting holes that allows a PT Series stage to be mounted vertically. This is necessary in all XZ and XYZ configurations. The adapter plate includes four 1/4"-20 (M6) cap screws. It is also compatible with our manual and motorized MT Series translation stages that offer 1/2" (12.7 mm) of travel. This allows stages with different travel ranges to be easily connected within the same mechanical system.

A CMOS (Complementary Metal-Oxide-Semiconductor) sensor is an image sensor that uses a matrix of photodiodes to convert light into an electrical signal. They are widely used in digital cameras and offer high image quality.

We offer vertical translation stages with crossed-roller bearings for precise motion as well as long travel vertical stages for heavy-duty applications.

The differential adjustment provides 25 µm of translation per revolution over a 250 µm range. The dfferential adjustment knob features graduations every 0.5 µm. Two 1/4"-20 (M6) counterbores allow the stage to be directly attached to a breadboard or mounting adapter (sold below) with user-supplied cap screws. Each stage contains sixteen 1/4"-20 (M6) tapped mounting holes that are 0.22" (5.8 mm) deep.

The PT Series of translation stages can be purchased individually (PT1 Series above) or as fully assembled, 3-axis, XYZ translators (PT3 Series). Therefore, the PT3 stage can be disassembled using a 3/16" (5 mm) hex key to customize the positions of the micrometers or to use three PT1 stages separately, see the XYZ Assembly tab for details.

The PT101(/M) and PT102(/M) are adapter plates designed for the PT Series translation stages. The PT101(/M) has four 1/4"-20 (M6) mounting slots on the side that enable obstruction-free mounting onto an optical breadboard. It is ideal for XY configurations or already assembled XYZ multi-axis configurations where the standard counterbores in the middle of the stages are obstructed. This base plate includes two alignment dowel pins and two 1/4"-20 (M6) cap screws.

Programming references that provide introductions to communicating with the DM713 Digital Micrometer (Figure 3) are available. One reference has been developed for LabVIEW, and the other for Visual C#. Each reference includes a step-by-step discussion for writing the program, as well as a section that concisely provide the full program text without explanation.

For applications that require increased resolution, the PT1A(/M) translation stage is configured with the DM12 differential adjuster. The coarse adjustment, which can be locked using a thumbscrew on the mounting collar, provides 0.5 mm of translation per revolution over a range of 1.00" (25.4 mm).

Digital microscopes are becoming increasingly popular due to their ease of use and ability to capture images and videos. Digital microscopes use a digital camera to capture images, and the lenses used are the CMOS and CCD sensors.

Each stage comes with two precision dowel pins that allow the PT series of translation stages to be stacked in right- or left-handed XY configurations with excellent orthogonality of <5 mrad. The right-handed XYZ configuration, with either the standard manual micrometer or the differential micrometer, is available fully assembled below.

Please contact technical support if your application would benefit from a stage that is equipped with imperial taps and metric micrometer drives or vice versa.

These translation stages feature hardened steel linear bearings for precise motion and long life. They are available with a variety of actuators and in single-axis or preassembled multi-axis configurations.

Attach the second, orthogonal PT series translation stage, as shown above, using two 1/4"-20 (M6) cap screws. Then insert the two 1/8" alignment pins into the provided holes for aligning the angle bracket.

Fixed lenses, also known as turret lenses, have a fixed magnification and cannot be adjusted. They provide a high-quality image but have limited versatility.
