The 48-622 is a Neutral Density Filter, specifically designed for use in the UV-VIS spectrum, with a diameter of 12.5 mm and a thickness of 1.5 mm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is identified by the Material ID "uvfs mal- 1965".
The filter's primary function is to reduce the intensity of light without altering its color composition. This is achieved through the use of a metallic-based coating on both the front and back surfaces, designated as "edm 48-622". This coating provides an Optical Density (OD) of 1.5, which corresponds to a reduction of 96.875% of the incident light in the wavelength range of 250-700nm.
The filter is designed in a Thin Lens shape, which minimizes optical aberrations and distortions, ensuring high-quality imaging and light transmission. The 48-622 is currently in stock and available for purchase through the vendor's website, as indicated by the "weblink status" field.
