NDUV2R40B Dia. 50 mm Unmounted UVFS Reflective ND Filter; OD 4.0
The NDUV2R40B is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 50 mm. This filter is unmounted, providing users 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 contributes to its durability and stability within optical setups. The NDUV2R40B is coated on both the front and back with THo NDUV OD4, a specialized coating that provides an Optical Density (OD) of 4.0. This high OD ensures a significant reduction in light intensity, providing superior protection for sensitive optical components.
The filter's shape is classified as Thin Lens, indicating its potential use in applications where a thin, lightweight lens-like component is required. The NDUV2R40B is currently in stock and available for purchase through the vendor's website, as indicated by its weblink status.
