TECHSPEC High Contrast Plastic Linear Polarizers are ideal for a variety of imaging applications. Offered in multiple sizes, these linear polarizers feature an excellent extinction ratio and high transmission of unpolarized light from 400 – 700nm. TECHSPEC High Contrast Plastic Linear Polarizers offer increased durability compared to polarizing film.
When unpolarized light enters a linear polarizer, the light that is polarized perpendicular to the polarization axis is absorbed, and light parallel to the polarization axis is transmitted. TECHSPEC High Contrast Plastic Linear Polarizers utilize a stretched PVA film to create the polarization axis. To increase durability, the film is then laminated between two plastic plates.
Note: These linear polarizers are not recommended for laser applications.
