Silver-nanoparticle thin-film linear polarizer, operating wavelength 480 nm-550 nm, extinction ratio >10000:1@480 nm-550 nm, thickness 2.0 mm.
Overview
Mounted version of LBTEK nanoparticle thin-film linear polarizer, housed in an SM1 lens tube with internal/external threads compatible with standard Ø25.4 mm (1 inch) optomechanics. Features the same embedded silver nanoparticle film providing high extinction ratio, high damage threshold, and wide operating temperature range across ±20° AOI.
Key Features

- Operating wavelength: 480 nm-550 nm
- Damage threshold: CW linearly polarized, perpendicular to transmission axis: 1 W/cm²; CW linearly polarized, parallel to transmission axis: 5 W/cm²
- Angle of incidence: 0°±20°
- Operating temperature: -20°C ~ 120°C
- Surface finish: 40/20
Applications
- Polarization control in scientific and industrial optical systems
- High-contrast imaging and spectroscopy
- Laser polarization filtering
- Applications requiring elevated operating temperature or laser damage threshold
