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.

Dielectric Mirrors offer near total reflection, minimizing losses in nearly all optical systems. AOI=45°, R>99.5% (Rs>99.9%, Rp>99.2%). AOI=0°, R>99.8%

Precision Aspheric Lenses Collimate or Focus Light with a Single Element Reduce spherical aberration Reduce overall system weight

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

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

Elliptical Shape Mirrors Made of by Fused Silica or N-BK7 Coated by Dielectric coating or metal (Al, Au, Ag)coating Shape could be customized
