In order to make the optical system has a good image quality objective ocular and other
system consisting of two or more lens prisms and other parts in order to make convenience
and protection also use combination. Combination way including the commonly used rubber
agglutination and separate lens combination special circumstances also run optical glue.

*CaF2 Ge and ZnSe Substrates
*Ray Deviation of 90°
*Ideal for Use with Collimated Sources
Infrared (IR) Right Angle Prisms are available in three substrate options. Calcium Fluoride is a low index (1.434) material with excellent transmission from 0.19 - 7μm making it ideal for applications throughout the UV Visible and Infrared spectra. Germanium is a dense material with a high index (n10.6μm = 4.0034) making it ideal for applications from 3 - 12μm where the optical path length needs to be maximized. Zinc Selenide (n10.6μm = 2.4028) is commonly used with CO2 laser applications and features high transmission from 1 - 16μm.
Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism the image may be inverted or reverted. Right angle prisms can also be used in combination for image/beam displacement.
Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.

Zinc Selenide Plano-Convex (PCX) Lenses
*Usable Transmission Range is 600nm to 16μm
*Low Dispersion
Zinc Selenide is a chemically vapor deposited material commonly used in thermal imaging FLIR and medical systems. It has wide usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock. Zinc Selenide is a relatively soft material that scratches easily and it is not recommended for use in harsh environments (Knoop Hardness 120). Great care must be taken during handling mounting and cleaning. Apply uniform pressure when handling wear Latex finger cots or gloves to prevent contamination and do not use tweezers or other tools.

Infrared Windows are flat plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Infrared Windows should be selected based on the material transmission or mechanical properties of the substrate. Infrared Windows do not cause change in the magnification of a system. Infrared Windows are offered in a variety of substrates such as Germanium (Ge) Silicon (Si) and Zinc Selenide (ZnSe) etc. Multiple anti-reflection coating options are available for the Infrared (IR).

YVO4
The Yttrium Orthovanadate (YVO4) is a positive uniaxial crystal grown with Czochralski method. It has good temperature stability and physical and mechanical properties. It is ideal for optical polarizing components because of its wide transparency range and large birefringence. It is an excellent synthetic substitute for Calcite (CaCO3) and Rutile (TiO2) crystals in many applications including fiber optic isolators and circulators interleavers beam displacers and other polarizing optics(refer to table 1).
