Achromats consist of two or more elements, usually of crown and flint glass, that have been corrected for chromatic aberration with respect to two selected wavelengths. They are also known as achromatic lenses. This area includes micro achromats as well.

Beam expanders are optical lens assemblies that are used to increase the diameter of a laser beam or other light beam.
|
|
Calcite polarizers are crystals used to separate unpolarized light into two separate plane polarized beams.
|

Color filters include a wide range of filter types that are distinguished by their specific color spectrums and wavelengths, as well as their Schott glass compositions.
|
|
Cylindrical lens have at least one surface that is formed in the shape of a cylinder. Cylindrical lenses are used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line. This area includes micro cylindrical lenses as well.

Depolarizers obliterate the polarization of a polarized beam by reflecting the beam in all directions at right angles to its axis.

|
Etalons are two flat glass plates separated by a parallel spacer, with the inner surfaces of the plates coated with a partially reflecting layer.

Fiber optic light guides are bundles of optical fibers used for the controlled deliver of light. They tend to be more rigid, and transmit well in both the visible and near-infrared (near-IR) regions of the electromagnetic spectrum. Fiber optic light guides are sometimes called fiber optic light pipes (fiber optic lightpipes).

Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry.

|
Flat mirrors are smooth, highly polished, flat surfaces, for reflecting light. The actual reflecting surface is usually a thin coating of silver or aluminum on glass.
|
|
Hot mirrors and cold mirrors are dichroic filters that have a sharp transition between rejecting and transmitting at the near-infrared-visible area of the spectrum.
|
|
Laser mirrors are designed for high reflectance and durability at individual laser wavelength ranges.

|
Lens holders are used to stabilize and maintain the position of all the optical components of a lens assembly.

Light guides conduct the flow of light from a light source to a point of use in areas that are too small or too hazardous to permit the installation of a light bulb. There are two basic types of light guides: liquid and fiber optic. Light guides are sometimes called light pipes (lightpipes).

Linear polarizers transmit light waves along one axis and absorb them along the other. The transmitting and absorbing axes of linear polarization are oriented at 90 degrees to each other.
|
|
Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation.
|
|
Mirror mounts are used to hold and support mirrors of all sizes and shapes.
|
|
Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters.
|
|
Nonpolarizing cube beamsplitters provide a true 50/50 split regardless of the incoming polarization. They consist of a pair of precision right-angle prisms carefully cemented or mounted together to minimize wavefront distortion.
|
|
Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.
|
|
Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems.
|
|
Optical lens assemblies are composed of a number of lenses mounted for a particular imaging function. These can include objectives, collimators, gauging lenses, etc.
|
|
Optical lenses are transparent components made from optical-quality materials and curved to converge or diverge transmitted rays from an object. These rays then form a real or virtual image of the object. This area includes micro lenses.
|
|
Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass.
|
|
Optical mounts are specialized holders designed for use with a variety of optical assemblies.
|
|
Optical polarizers are optical devices that can transform unpolarized or natural light into polarized light, usually by the selective transmission of polarized rays.
|
|
Optical prisms are blocks of optical material with flat, polished sides that are arranged at precisely controlled angles to one another. They are used in optical systems to deflect or redirect beams of light. They can invert or rotate images, disperse light into component wavelengths, and separate states of polarization.
|
|
Optical rails and optical bases mount to optical tables to support components and instruments in a straight line, while retaining the freedom to quickly change their relative spacing.
|
|
Optical windows are used to isolate different physical environments while allowing light to pass relatively unimpeded.
|
|
Pellicle beamsplitters are constructed from thin, nitrocellulose films that are stretched and cemented to rigid supporting rings. They are very delicate and liable to resonate to certain vibration frequencies.
|
|
Plate beamsplitters are semi-mirrors, which reflect part of the incident energy (absorb a relatively small part) and transmit the rest. Some are neutral and some are spectrally selective.
|
|
Polarization rotators maneuver incident-linearly-polarized light about an optical axis.
|
|
Polarizer mounts are used to hold and support polarizers.
|
|
Polarizing cube beamsplitters divide unpolarized light into two orthogonally polarized beams at 90° to each other. The transmitted beam is mostly polarized parallel to the plane of incidence (p-polarized), and the reflected beam is mostly polarized perpendicular to the plane of incidence (s-polarized).

|
Spherical lenses, also known as singlets, are transparent optical components consisting of one or more pieces of optical glass with surfaces so curved that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object. This area includes micro spherical lenses as well.
|
|
Spherical mirrors are curved so that reflected beams converge on a focal point.
|
|
Waveplates and retardation plates are optical elements with two principal axes, one slow and one fast, which resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form
