Product Description
Karl Lambrecht MGLA-17-DW-BB-532 Glan-Laser Polarizer – High Extinction Ratio, 532nm Wavelength
This used Karl Lambrecht MGLA-17-DW-BB-532 is a precision Glan-Laser polarizer designed for demanding laser applications. The MGLA series typically consists of two high-grade calcite prisms optically cemented or air-spaced to produce a highly collimated beam of linearly polarized light.
The “MGLA” designation generally indicates a Glan-Laser polarizer in a protective aluminum housing for high damage threshold. The “17” typically indicates a 17mm clear aperture, making it suitable for medium to large diameter beams.
Condition Note: This unit is used and sold as-is. It should be inspected for optical clarity and coating integrity.
