FNDU-20C02-20 20 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm
OptoSigma's FNDU-20C02-20 is a 20 mm diameter, unmounted Reflective Neutral Density Filter, designed for use in the ultraviolet spectrum, specifically between 200-400nm. This filter is part of the UVFS series, identified by the material ID 'uvfs mal- 1965'.
The filter is characterized by its thin lens shape, with a thickness of 2mm, making it an ideal choice for applications where space is a constraint. The front and back of the filter are coated with 'opt fndu-20', a coating that enhances its performance and durability.
This filter is a Neutral Density type, which means it reduces the intensity of light, regardless of its wavelength, without altering its color. This is particularly useful in applications where controlling light intensity is crucial, such as in photography, laser applications, and scientific research.
The filter's information is currently available on the OptoSigma website, and it is listed as 'in stock', indicating its immediate availability. For more detailed information or to make a purchase, users can follow the provided weblink.
