Working Wavelength: 400-700 nm
Mechanical Housing Models: CRM-05AS, CRM-1AS, CRM-2A
This thin film linear polarizer is ideal for low-power applications, offering high extinction ratios and a large angle of incidence. The transmission axis is aligned with the 0° marking on the rotating mirror frame, making it easy to use.
For the working wavelength of 400-700 nm, the air contact surfaces of the substrates on both sides of the thin film linear polarizer are coated with anti-reflection coatings for the corresponding wavelength bands. The polarizers, installed with retaining rings, are mounted in rotating mirror frames CRM-05AS, CRM-1AS, and CRM-2A, with clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm, respectively.
The thin film linear polarizer is suitable for low-power applications and provides a high extinction ratio and a large angle of incidence range of ±20°. The transmission axis of all three models is aligned with the 0° marking and is fixed with adhesive for ease of use.
