Product Description
  • Linear polarizing film/N-BK7 Window, sandwich flat structure, with mechanical housings
  • Uniform transmission direction within the component plane
  • Capable of generating linearly polarized light beams with specific polarization directions
  • High extinction ratio, large incident angles
  • Operating wavelength λ: 400-700 nm, 700-1700 nm
  • Custom services for parameter specifications available
The LBTEK Thin Film Linear Polarizer consists of front and rear N-BK7 glass substrates with a linear polarizing film sandwiched in between, offering two mounting options —the retaining ring and the rotation mirror mount. Across the entire component surface, the transmission axis remains consistent, making it suitable for generating linearly polarized light beams with specific polarization directions while ensuring the high extinction ratio and a wide range of incident angle. LBTEK provides thin film linear polarizers with operating wavelengths of 400-700 nm and 700-1700 nm, along with flexible customization of parameter specifications to meet diverse application requirements. For details, please consult LBTEK Technical Support.

Thin Film Linear Polarizers, 400-700 nm, With Retaining Rings for Mounting
  • Operating wavelength: 400-700 nm
  • Mechanical housing dimensions: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm
  • Suitable for low-power applications, high extinction ratios, large incident angles
  • Housings engraved with product models and transmission axis direction marking lines for easy use

The thin film linear polarizers with an operating wavelength range of 400-700 nm, have anti-reflection coatings on both air-contact surfaces of the substrates for corresponding wavelength bands. The thin film linear pilarizer with clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm respectively, are mounted in mechanical retaning rings with diameters of Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm. The thin film linear polarizer is suitable for low-power applications and offers high extinction ratios and a wide incidence angle range of ±20° when used to generate the linearly polarized light. All three product models are marked with the product numbers and transmission axis direction on the housings for convenient use by customers. Note: Due to product version updates, discrepancies may occur between the engraved markings on the housing and the actual product model. However, this does not affect product performance. Please feel assured in using the product.

Thin Film Linear Polarizer, 700-1700 nm, with Retaining Rings for Mounting
  • Operating wavelength: 700-1700 nm
  • Mechanical housing dimensions: Ø12.7 mm, Ø25.4 mm, Ø50.8 mm
  • Suitable for low-power applications, high extinction ratios, large incident angles
  • Housings engraved with product models and transmission axis direction marking lines for easy use

For thin film linear polarizers with a wavelength range: 700-1700 nm, the air-contact surfaces of the substrates on both sides are coated with Antireflection Coating (AR Coating) for the corresponding wavelength range. They are mounted in Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm Mechanical Engineering retaining rings, with Clear Aperture (CA) of Ø10 mm, Ø21.5 mm, and Ø45 mm, respectively. The thin film linear polarizer is suitable for low-power application scenarios. When used to generate linearly polarized light, it has a high Extinction Ratio (ER) and a large incidence angle range of ±20 °. All three products are marked on the housing with the Item and transmission axis direction, making them convenient for customers to use. Note: The thin film raw material has been updated, and the product Transmission and Extinction Ratio (ER) parameters have been adjusted accordingly; please refer to the spectral curve on the official website for details.
