FNDU-50C02-1 50 mm Dia. Unmounted UVFS Reflective Neutral Density Filter; t=2mm 200-400nm

The FNDU-50C02-1 is a 50 mm diameter, unmounted Neutral Density Filter, manufactured by OptoSigma. This filter is designed for use in the ultraviolet range, specifically between 200 and 400 nanometers.

The filter is made from UVFS material, identified as "UVFS Mal- 1965" in the item data. This material is known for its excellent transmittance in the UV range, making it ideal for applications that require precise control of UV light.

The filter has a thickness of 2mm, which is relatively thin compared to other filters in the market. This thinness can be beneficial in certain applications where space is a constraint.

The filter is coated on both sides with the OptoSigma FNDU-1 coating. This coating is designed to provide high neutral density, ensuring that the filter can uniformly reduce the intensity of light passing through it, without altering the color balance.

The filter is shaped as a thin lens, which is a type of optical component that focuses or disperses light. This shape can be advantageous in applications where light needs to be concentrated or spread out over a larger area.

The filter is currently in stock and available for purchase on the OptoSigma website. More information about this product, including pricing and availability, can be found at the provided weblink.
