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.

Glued prisms are glued by different shape prisms. WTS offer Special Prisms like Half Penta Prisms, Pellin-Broca Prisms, Pechan Prisms etc. prisms

Rhomboid prisms are commonly used to displace a laser beam without changing its direction. Lateral Displacement of Beam Displaces Optical Axis Without Inverting Image

Sapphire Windows Transmission in 0.3-5.0μm, no absorption in 2-3μm Extremely hard and durable High thermal conductivity High bulk damage threshold

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

LBO(Lithium Triborate LiB305) is a newly developed nonlinear optical crystal.It is unique in many aspects,especially its wide transprency range,moderately high nonlinear coupling,high damage threshold and good chemical and mechanical properties.
