NDUV2R03B Dia. 50 mm Unmounted UVFS Reflective ND Filter; OD 0.3
The NDUV2R03B is a Neutral Density Filter with a diameter of 50 mm, manufactured by Thorlabs. This unmounted filter is designed with a thin lens shape and a thickness of 2 mm, making it a compact and convenient option for various optical applications.
The filter's primary function is to reduce the intensity of incident light without altering its color composition. This is achieved through the application of a front and back coating of THORNDUV OD0.3, a specialized coating that provides a neutral density of 0.3. This coating ensures consistent light reduction across the entire spectrum, from 300 nm and above.
The material used in this filter is UVFS, a unique material with a catalog number of NDUV2R03B. This material is specifically designed for use in UV applications, ensuring high transmittance and minimal absorption in the UV range.
The filter is available for purchase through the Thorlabs website, where it is listed as in stock. Further information about this product, including technical specifications and purchasing options, can be found at https://www.thorlabs.com/thorproduct.cfm?partnumber=NDUV2R03B.
