Optics & Optical Coatings
Mirrors can be used for reflecting as much beam of light as possible. They have two different coatings by metal and dielectric materials.
Beamsplitters can be used for dividing light beam. They have two different coatings by metal and dielectric materials.
Filters fall into four groups, NDA filters that control light intensity, Color filters that control the wavelength of transmitted light by a light-absorbing substance, Dielectric ones that transmit the light with a wavelength of a particular value in the visible region and reflect the light of other wavelengths, and Interference ones that emit light at an arbitrary wavelength between a few and several nanometers.
Polarizers, made of quartz, calcite, crystals and polarizing films can be used for introducing a phase difference to a polarized beam and emitting a linearly polarized beam when an un-polarized beam is introduced.
Lenses can be used for collecting a parallel beam, collimating the light from point source to parallel beams and diffusing the collimated beam.
The product lineup of high performance designed lenses includes achromatic lenses whose abberations are previously corrected by two or three lenses, beamexpanders for expanding a laser beam in parallel ray, fθ lenses for collecting and scanning deflected beams from a scanner or a similar device on a flat image surface.
Prisms can be used for splitting a light into beams traveling in two different directions, for dispersing an incident light and for inverting the orientation of an image.
Windows are used for a transparent barrier so that a beam of light can be transmitted between two phases in the different environments.
Substrates are materials used for beamsplitters, windows, laser mirrors and etc. Master Optics are used for test glasses whose surface flatness are being measured by Zygo laser interferometer system. Its flatness is assured by providing the interferogram and the 3D chart.
