FNDU-50C02-40 50 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm
OptoSigma's FNDU-50C02-40 is a 50 mm diameter, unmounted, reflective neutral density filter. This filter is designed for use in the ultraviolet-visible-near infrared (UV-VIS-NIR) region of the spectrum, specifically between 200 and 400 nanometers.
The filter features a thickness of 2mm, providing a balance between durability and optical performance. It is made from UVFS, a material with a refractive index and dispersion characteristics suitable for UV-VIS-NIR applications.
The front and back surfaces of the filter are coated with Opt FNDU-40, a coating that enhances the filter's performance in neutral density applications. This coating helps to maintain a consistent transmission across the filter's spectral range, ensuring accurate and reliable optical performance.
The filter's thin lens shape allows for easy integration into optical systems, while its unmounted design provides flexibility in choosing the right mount for your specific application. The filter is currently in stock and available for purchase through the OptoSigma website.
