FNDU-20C02-50 20 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm

OptoSigma's FNDU-20C02-50 is a 20 mm diameter, unmounted UVFS reflective neutral density filter, designed for use in the ultraviolet spectrum. This filter is part of the OptoSigma family of reflective neutral density filters, which are known for their high-quality optical performance and durability.

The filter is made from UVFS material, which is specifically designed for use in the ultraviolet spectrum. It has a thickness of 2mm and is coated with Opt FNDU-50 on both the front and back surfaces. This coating provides a high level of neutral density, reducing the intensity of light while maintaining the color balance.

The FNDU-20C02-50 is designed to transmit light in the 200-400nm range, making it ideal for use in applications such as UV spectroscopy, UV imaging, and other UV-based scientific research. The circular shape and thin lens design of the filter make it easy to integrate into optical systems, while the unmounted design allows for flexibility in how it is used.
