NDUV20B Dia. 25 mm Unmounted UVFS Reflective ND Filter; OD 2.0
The NDUV20B is a circular Neutral Density Filter, unmounted, with a diameter of 25 mm and a thickness of 1 mm. This filter is sourced from Thorlabs, a reputable vendor in the optical industry, and is part of their UVFS series, specifically identified as UVFS Mal-1965.
The NDUV20B filter is designed with a UVFS coating on both the front and back, specifically the THo NDUV OD2 coating. This coating is engineered to provide a high level of neutral density, with an Optical Density (OD) of 2.0. This means that the filter reduces the intensity of incident light by a factor of 100, making it an ideal choice for applications where significant light reduction is required.
The filter's geometry is shaped in a Thin Lens design, which is beneficial for applications where minimal optical path difference is crucial. The wavelength for this filter is 300 nm, indicating its suitability for ultraviolet light applications.
The NDUV20B filter is currently in stock and available for purchase through the vendor's website, as indicated by its weblink status. For more detailed information or to make a purchase, users can follow the provided weblink.
