Neutral Density Filter, 0.1 Optical Density, 1.0 in. Diameter
The 5231 Neutral Density Filter is made with an Inconel® metallic coating on a glass substrates. This 1.0 inch (25.4 mm) diameter ND filter provides 0.1 OD spectrally uniform attenuation over the wavelength range from 400 to 2000 nm. The reflective nature of the coating helps reduce thermal effects when this filters are used with moderate power lasers.
