Mechanical Housing Sizes: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm
The thin film linear polarizer is suitable for low power applications, offering high extinction ratios and a large angle of incidence. The housing is engraved with the product model and transmission axis direction marking lines for ease of 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. It is installed in mechanical retaining rings with sizes of Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm, with clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm, respectively. The thin film linear polarizer is ideal for low-power applications, with a high extinction ratio and a large angle of incidence range of ±20°.
The product model and transmission axis direction are marked on the housing of all three models, making it easier for customers to use.
Note: Due to the replacement of old and new products, there may be discrepancies between the engraved model number and the product model on the housing, but this does not affect the product performance. Please use with confidence.
