 ■ Glan-Laser Polarizer
Glan Polarizer is made of two Select-Grade Calcite Prism pair with the prism interface angles optimized for minimum insertion loss, which are assembled with Air-Spaced. Glan Laser Polarizer has two escape windows that allow the rejected beam to escape out of the polarizer. Normally they can be used in Q-switched laser cavities and other multiple pass applications.

Beam Expander

A beam expander is any optical system designed to increase the diameter of a laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.

Variable Attenuator

CNI provide two kinds of variable attenuators for different application. The circular variable attenuator can make the optical density linearly varies around a 0°-270° circle for measuring laser energe farthest. As for the square one, the optical density linearly varies across the length for measuring laser energe.
