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.

The product lineup of high performance designed lenses includes achromatic lenses whose aberrations 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.

Mirrors can be used for reflecting as much beam of light as possible. They have two different coatings by metal and dielectric materials.

Lenses can be used for collecting a parallel beam collimating the light from point source to parallel beams and diffusing the collimated beam.

Beamsplitters can be used for dividing light beam. They have two different coatings by metal and dielectric materials.

Windows are used for a transparent barrier so that a beam of light can be transmitted between two phases in the different environments.

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices.

Banner Union manufactures and supplies Scintillation Crystal.

Polarizer is an important optical component that is widely used in optics to produce a state of linear polarization. Banner Union provides polarizers with three materials, α-BBO, calcite and VYO4, making them suitable for the widest spectrum and high polarization purity application.
