Survey Prisms are for Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.

True Zero Order Waveplates  1. Constructed of a true zero order waveplate and a BK7 substrate.As the waveplate is very thin and easy to be damaged,the Bk7 plate's function is to strengthen the waveplate.  2. Single Plate

Fused Silica material Advantages With Good UV and IR transmission, Low thermal expansion, providing stability and resistance to thermal shock, Wider thermal operating range and High laser damage threshold make Fused Silica windows could used for Laser, Medical, imaging etc. application.

KDP&DKDP Crystal are commonly used for doubling, tripling and quadrupling of Nd:YAG laser at the room temperature.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.

Optical Aluminum Coated Mirrors Average Reflectance >88% from 450 nm to 10 µm Shape could be customized: Round, Square, Elliptical, Right angle prisms Material could be customized: Fused silica, Pyrex, N-BK7
