NDUV501B Dia. 0.5 in Unmounted UVFS Reflective ND Filter; OD 0.1
The NDUV501B is a circular Neutral Density Filter, unmounted, with a diameter of 0.5 inches and a thickness of 1 millimeter. This filter is sourced from Thorlabs, a renowned vendor in the optical industry, and is part of their UVFS reflective series with the material ID 1965.
The NDUV501B is designed to reduce the intensity of incident light without altering its color composition, making it an ideal tool for managing light intensity in various optical applications. The filter's Neutral Density (ND) value is Od 0.1, indicating a 10% transmission of light.
The front and back surfaces of the filter are coated with Thorlabs' NDUV coating, specifically the THo NDUV OD01 coating. This coating enhances the filter's performance by providing a uniform and consistent attenuation of ultraviolet light.
The filter's geometry is shaped as a thin lens, which is beneficial for applications that require minimal optical path deviation. The NDUV501B is currently in stock and available for purchase through the vendor's website, as indicated by its weblink status.
