NDUV2R20B Dia. 50 mm Unmounted UVFS Reflective ND Filter; OD 2.0

The NDUV2R20B is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 50 mm. This filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems. The filter's primary function is to reduce light intensity without altering the color composition of the incident light, making it an essential component in various optical applications.

The filter features a UVFS material ID (mal- 1965) and is designed to operate at a wavelength of 300 nm. It has a thickness of 2 mm, which is considered thin in the context of optical components, thereby minimizing the potential for optical aberrations. The NDUV2R20B is coated with THo NDUV OD2 on both the front and back surfaces, which contributes to its neutral density performance.

The NDUV2R20B's shape is described as a Thin Lens, indicating that it has been designed with minimal thickness and curvature to reduce optical aberrations. This feature makes it an ideal choice for applications that require high-precision optical components.
