Linear Film Polarizers — Model FLP51-NIR-M
Mounted linear film polarizer, 700–1700 nm, Ø50.8 mm housing, extinction ratio >5000:1, ±20° AOI
Overview
The Linear Film Polarizer (FLP) consists of front and rear N-BK7 glass substrates with a linear polarizing film sandwiched in between, offering two mounting options: retaining ring mount and rotation mirror mount. Across the entire component surface, the transmission axis direction remains consistent, making it suitable for generating linearly polarized light beams with a specific polarization direction while ensuring a high extinction ratio and a wide incidence angle range. Linear film polarizers are available with operating wavelengths of 400–700 nm and 700–1700 nm, and flexible customization of parameter specifications is supported to meet user requirements.
Key Features
- Linear polarizing film / N-BK7 window in sandwich flat structure with mechanical housings

- Capable of generating linearly polarized light beams with specific polarization directions
- High extinction ratio (>5000:1 at peak range), wide incidence angle range of ±20°
- Operating wavelength: 400–700 nm (VIS) and 700–1700 nm (NIR)
- Custom services for parameter specifications available
Applications
- Laser beam polarization control and analysis
- Optical isolation and attenuation (crossed-polarizer configuration)
- Polarization microscopy and imaging systems
