FNDU-50C02-50 50 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm
OptoSigma's FNDU-50C02-50 is a 50 mm diameter, unmounted, reflective neutral density filter. This filter is designed for use in the ultraviolet region of the spectrum, specifically between 200 and 400 nanometers.
The filter features a uniform thickness of 2 millimeters, providing a consistent optical path length. It is made from UVFS material, identified as "uvfs mal- 1965" in the item data, which is specifically designed for use in the ultraviolet region.
The filter's coating is another notable feature. Both the front and back surfaces are coated with "opt fndu-50", a coating that likely contributes to the filter's neutral density and reflective properties.
The filter's geometry is that of a thin lens, suggesting that it is designed to minimize optical aberrations and distortions. This makes it suitable for use in precision optical systems where high image quality is required.
According to the item data, this filter is currently in stock and can be purchased directly from the vendor's website.
