Polarization Film VIS
The LINOS® Polarization Film VIS is a high-performance linear polarizing polymer film designed for precise optical applications across the visible spectrum. Its broad visible wavelength coverage makes it ideal for demonstrations, optical testing, and stress analysis, as well as for continuously attenuating linearly polarized light across a constant clear aperture. The film achieves an excellent balance between high transmittance and superior extinction ratio, ensuring minimal light loss while maintaining precise polarization control. The film is cost-effective, lightweight, and flexible, making it easy to handle and integrate into various setups.
The Polarization Film VIS is suitable for moderate light intensities and broadband illumination, providing a high degree of polarization with consistent, reproducible performance. It is available in both unmounted and mounted versions for use in laboratory and educational settings.
