12.5mm Dia. HC VIS-NIR Polarizer, Mounted

Product Details Multiple Wavelength Ranges for UV, VIS and NIR >100,000:1 Contrast Ratios Available Ideal for Use in Harsh Environments UV, VIS-NIR, and NIR High Contrast Polarizers offer both versatility and performance over a wide range of wavelengths. These polarizers contain uniformly stretched silver nano-particles in a 220 ±25μm thick soda-lime glass laminated on a thicker soda-lime substrate for increased durability. UV, VIS-NIR, and NIR High Contrast Polarizers are ideal for harsh environments, can withstand up to 120°C, are resistant to UV-radiation and chemicals, and can be safely used in humid environments.
