Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity. 

Surface profilometers are contact or non-contact instruments used to measures surface profiles, roughness, waviness and other finish parameters.

Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components. Surface texture and topology characteristics include surface roughness, contour, form, waviness and defects.

Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources.

Optical flats or test plates are polished surfaces that are used as references against the flatness of unknown surfaces for comparison. They use the property of interference to measure the flatness of a test surface

Planing tools are used for surfacing planing on flat surfaces and gear teeth.

Dimensional and profile scanners gather two-dimensional (2D) or three-dimensional (3D) information about an object.

Dimensional measurement and metrology services use mechanical gaging, CMM measurement, non-contact imaging or other specialized methods to inspect and measure part dimensions and geometry.

Optical tables and breadboards effectively dampen working surfaces with superior flatness. They are used in the precision mounting of optical components

Finishing compounds are used to improve surface finish or flatness. They often consist of fine abrasives in slurry, bar, powder or paste forms

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.

Polka dot beamsplitters consists of an ultraviolet grade fused silica substrate with a vacuum deposited aluminum coating applied in a manner that gives the beamsplitter a polka dot appearance. They have a constant 50/50 reflection-to-transmission ratio over a large spectral range.

Chemical additives and agents include a wide range of materials added to polymer resins, paints and coatings, or adhesives to modify specific processing or end-use properties.

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 windows are used to isolate different physical environments while allowing light to pass relatively unimpeded.
