FNDU-25C02-60 25 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm
The FNDU-25C02-60 is a 25 mm diameter, unmounted Neutral Density Filter, sourced from the renowned optical component manufacturer, OptoSigma. This filter is designed for use in the ultraviolet region of the spectrum, specifically between 200-400nm, making it ideal for applications that require precise control of UV light.
The filter is constructed with a UVFS material, identified as 'UVFS mal- 1965', and features a thickness of 2mm. This combination ensures high durability and reliability, making the FNDU-25C02-60 suitable for a wide range of optical setups.
The filter's coating is another notable feature. Both the front and back surfaces are coated with 'opt fndu-60', a reflective neutral density coating. This coating enhances the filter's performance by reducing the amount of light that passes through, thereby providing better control over the intensity of the UV light.
The FNDU-25C02-60 has a circular shape and a thin lens geometry, which contributes to its ease of integration into various optical systems. The filter is currently in stock and available for purchase through the OptoSigma website, as indicated by its 'Valid - in stock' weblink status.
