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.
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 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 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.
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.
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
