FNDU-30C02-80 30 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm

OptoSigma's FNDU-30C02-80 is a 30 mm diameter, unmounted UVFS reflective neutral density filter, designed for use in the ultraviolet spectrum. This filter is part of the Neutral Density Filter category and features a thin lens shape with a thickness of 2mm.

The filter's primary function is to reduce the intensity of light entering the optical system without altering its color composition. This is particularly useful in high-intensity light situations, such as when working with lasers or other powerful light sources.

The filter is made from UVFS material, which is specifically designed for use in the ultraviolet spectrum, covering the wavelength range of 200-400nm. This makes it ideal for applications that require precise control over ultraviolet light.

The front and back of the filter are coated with Opt FNDU-80, a reflective coating that enhances the filter's performance and durability. This coating helps to minimize reflections and scatter, improving the overall quality of the light that passes through the filter.

The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems in a way that best suits their specific needs. This also allows for easy replacement or upgrade of the filter as needed.
