NDUV2R13B Dia. 50 mm Unmounted UVFS Reflective ND Filter; OD 1.3

The NDUV2R13B is a Neutral Density Filter with a diameter of 50 mm, manufactured by Thorlabs. This unmounted filter is designed with a UVFS material ID, specifically mal-1965, and features a thin lens shape. The filter's primary function is to reduce light intensity without altering the color composition of the light source.

The filter's coating is consistent on both the front and back surfaces, featuring a THo NDUV OD13 coating. This coating is designed to provide a neutral density of 1.3 optical density (OD), which corresponds to a transmission of approximately 12.5%. This makes it suitable for applications where a significant reduction in light intensity is required.

The geometry of the filter includes a thickness of 2 mm, which contributes to its durability and stability. The filter's diameter of 50 mm is a standard size, making it compatible with a wide range of optical systems and components.

The filter's catalog number is NDUV2R13B, and it can be found on Thorlabs' official website. The link provided in the item data indicates that the filter is currently in stock, ensuring quick and efficient delivery for your optical needs.
