Thin Film Linear Polarizers — Model FLP51-VIS-M
Mounted thin film linear polarizer, 400–700 nm, Ø50.8 mm housing, extinction ratio >5000:1, ±20° AOI
Overview
The LBTEK Thin Film Linear Polarizer (Film Linear 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. LBTEK offers thin film linear polarizers with operating wavelengths of 400–700 nm and 700–1700 nm, and also supports flexible customization of parameter specifications to meet user requirements.
Key Features
- Linear polarizing film / N-BK7 window in 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 (>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
- Spectroscopy and interferometry setups
- Quality inspection and materials characterization
