Our 200mm stages, remove travel resrictions in lab-scale applications. Whereas, in tasks such as heavy load transport, automated assembly lines, and the manipulation of oversized components, even longer stages are used.

Whether you are involved in microscopy, spectroscopy, or metrology, a linear stage can be an invaluable tool. The decision to invest in a linear stage depends on the specific requirements of your application.

High precision linear stages provide a higher level of accuracy and repeatability. They incorporate advanced components, such as C5 ball screws, to achieve reduced error values.

Laser power detector for measurement up to 50 000 W that traps > 97 % of the incident light and handles high intensities of small beams.

Designed for movement along a single axis, X linear stages enable precise, horizontal movement. They are crucial components in various applications that require precise positioning in one dimension, including optical component alignment, materials handling, and other basic positioning tasks.

Sample positioning, optical component alignment, and basic materials handling are a few of the applications that often employ standard precision linear stages. They offer a balance between accuracy and affordability, making them accessible for various applications where tight tolerances are not critical.

In sectors where the strictest tolerances are essential, including semiconductor manufacturing, microscopy, and nanotechnology, these stages are essential.

While some multi-axis stages are integrated, our systems are modular. This means you can combine multiple stages to achieve multi-axis motion, or use them independently in simpler positioning tasks.

Laser Aperturemachine

When you consider a circular Gaussian laser beam, each wavefront that it creates has (theoretically) a certain value of energy everywhere in the universe. So, if the laser beam goes through an aperture, no matter how big the aperture actually is, there is a certain amount of energy from the incident laser beam that does not go through. Knowing the diameter at 1/e² of your laser beam will then make it possible to calculate the resulting power that is passing through an aperture. As one could expect, the bigger the aperture, the more negligible becomes the proportion of the power that is blocked. This is of importance when using detectors, mainly because having an inappropriate aperture dimension would lead to inaccurate measurements of either power or energy. This is also true when thinking about optical designs of new technologies. Finally, depending on how crucial your accuracy of measurement needs to be (and how good you are at centering your beam on the detector), as a rule of thumb, aim for an aperture that is double the size of the beam at 1/e². At this point, you’ll already have more than 99.9% of that incident beam power going through the aperture (if perfectly centered).

Linear stage systems can have an array of features and specifications. With this, precise linear motion can be implemented into a wider variety of applications.

Our linear stages are equipped with an intelligent stepper motor controller and intergrated rotary encoder. This enables you to move equipment and samples precise distances easily.

Manual linear stages are mechanically adjusted by hand. When you turn the handle, the carriage moves along a straight path. They are straightforward and cost-effective solutions for applications where automation is not required.

The formulas describe the behavior of a perfectly circular Gaussian laser beam. In such, they represent an approximation of the values one would obtain in real conditions. The diameter value that is used for the beam refers to the 1/e² parameter. We also assume that the laser beam is perfectly centered in the aperture, making the beam and the aperture two concentric circles. Also, one should know that the diameter of a Gaussian beam is a function of z. Therefore, its value is different according to the point where it is measured. This refers to more complex physicals concepts relative to the propagation of a Gaussian beam in space which will not be discussed here.

For more advanced applications, XYZ stages offer precise three-dimensional motion. You can use these systems in various complex applications, including 3D printing, medical imaging, and microscopy.

While lacking the precision and automation of motorized stages, manual linear stages find utility in educational settings, prototyping, and situations where simplicity and budget constraints are paramount.

Long travel linear stages enable extended linear motion over greater distances. They often feature larger dimensions and a robust construction to accommodate extended travel lengths, from 200mm to several meters.

Equipped with electric motors for automated and highly accurate linear motion, motorized linear stages offer controlled and repeatable positioning. They are ideal for industrial automation, semiconductor manufacturing, microscopy, and scientific research.

For two-dimensional motion, XY stages are used. Intricate tasks such as circuit board inspection, sample manipulation in scientific research, and material procssing, are possible with XY stages.

Standard precision linear stages focus on reliability and cost-effectiveness. Their drive mechanism provides moderate precision, typically in the range of micrometers to a few tens of micrometers. In our standard precision stages, we use a C7 ball screw drive.
