Align CO₂ and other infrared laser beam delivery systems with these dichroic beamsplitters that transmit IR and reflect HeNe or visible wavelength diode-laser beams.

Coarse and Fine Focus knobs are used to focus the microscope. Increasingly, they are coaxial knobs - that is to say they are built on the same axis with the fine focus knob on the outside. Coaxial focus knobs are more convenient since the viewer does not have to grope for a different knob.

Meniscus lenses are the "best form" single-element optic for ZnSe due to its high refractive index. Thus, they offer smaller focused spot sizes than plano-convex lenses yet are less costly than aspheric lenses since they are easier to manufacture.

Choose a standard lens or specify exactly the component you require. Our extensive inventory of test plates and tooling minimizes fabrication costs for custom items.

Objective Lenses are the primary optical lenses on a microscope. They range from 4x-100x and typically, include, three, four or five on lens on most microscopes. Objectives can be forward or rear-facing.

Learn about the vertically integrated capabilities for material growth, fabrication, coating, and assembly, and rigorous QA at Coherent. Discover how these ensure the performance and reliability of our optics and minimize supply chain risks and uncertainties.

Obtain polarized laser output or achieve lossless transmission of p-polarized light using these plane parallel windows, designed for operation at Brewster's angle.

Nosepiece houses the objectives. The objectives are exposed and are mounted on a rotating turret so that different objectives can be conveniently selected. Standard objectives include 4x, 10x, 40x and 100x although different power objectives are available.

Learn how we are enabling the next generation of high-speed optical transmission systems, networks, and datacenter solutions.

Protect valuable scan lenses and focusing optics in industrial laser systems from debris, backspatter, and other workplace hazards with these plane parallel windows.

A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially, a compound microscope consists of structural and optical components. However, within these two basic systems, there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated and explained below.

The Coherent HyperRapid NXT 266 is the world's first industrial-grade deep UV, picosecond laser, offering extraordinary precision manufacturing as small as 5 µm.

Condenser is used to collect and focus the light from the illuminator on to the specimen. It is located under the stage often in conjunction with an iris diaphragm.

Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality microscopes include an Abbe condenser with an iris diaphragm. Combined, they control both the focus and quantity of light applied to the specimen.

Stage is where the specimen to be viewed is placed. A mechanical stage is used when working at higher magnifications where delicate movements of the specimen slide are required.

Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base.

Extend the lifetime of optics that require frequent cleaning from exposure to metal spatter and debris in drilling, cutting, and marking applications.

Transmit infrared light and laser beams with minimal loss and wavefront distortion using these precision, anti-reflection coated, plane parallel windows.

Eyepiece Tube holds the eyepieces in place above the objective lens. Binocular microscope heads typically incorporate a diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. The monocular (single eye usage) microscope does not need a diopter. Binocular microscopes also swivel (Interpupillary Adjustment) to allow for different distances between the eyes of different individuals.

Stage Clips are used when there is no mechanical stage. The viewer is required to move the slide manually to view different sections of the specimen.

Process materials with increased efficiency using the diffraction-limited focused spots achievable with these precision aspheric lenses.

Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x.
