The 62-672 is a 50 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with an Optical Density (OD) of 0.3. This filter is sourced from the reputable optical vendor, Edmund Optics.
The filter is circular in shape, made from a metallic based material, and has a thickness of 5 mm. It features a thin lens shape, which is beneficial for applications requiring minimal optical path deviation. The filter's coating, both on the front and back, is EDM 47-825, which is a proprietary coating developed by Edmund Optics for this specific filter type.
The filter's primary function is to reduce the intensity of light without altering its color composition. This is particularly useful in NIR applications where controlling light intensity is crucial. The filter's NIR specificity, with a central wavelength of 588 nm, makes it ideal for use in systems operating within the 700-1100nm spectral range.
