OEM Liquid Crystal Variable Retarder
KEY FEATURES
- Precision control at lower cost
- Scalable quantities
- Thin housing
- Large clear aperture
- Usable from 450 to 1800 nm
DESCRIPTION
Meadowlark Optics is pleased to announce a small, mounted liquid crystal family of products intended for space constrained or OEM applications. By removing the temperature control circuitry, the overall dimensions of the housing can be significantly reduced. For even tighter mechanical constraints, unmounted cells are also available with flying leads or custom connectors.
