Metal Wire Grid Polarizer, 420–1100 nm
Mounting: Retaining ring mount
Mechanical Housing Sizes: Ø12.7 mm, Ø25.4 mm
Clear Apertures: Ø10 mm (for Ø12.7 mm housing), Ø21.5 mm (for Ø25.4 mm housing)
Coating: Both air-contact surfaces of the substrates are AR-coated for 420–1100 nm
Markings: Each housing is clearly engraved with the product model number and transmission axis orientation for user convenience
By rotating the output polarizer, the transmitted light intensity can be smoothly tuned. The output polarizer can be locked in place with an M3×2.5 flat-head setscrew tightened by an M1.5 hex key.
This variable polarizer is ideal for low-power applications where linear polarization is required, offering high extinction ratio performance and an incident angle range up to ±20°.
