The NDUV2R13A is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 50 mm. This filter is part of the UVFS series, specifically identified by the material ID "uvfs mal- 1965". It features a thin lens shape and a thickness of 2 mm, making it a compact yet effective optical component.
The filter's primary function is to reduce light intensity without altering the color composition of the light source. It has a wavelength of 300 nm, which is particularly useful in applications where ultraviolet light needs to be managed. The NDUV2R13A is coated with THo NDUV OD13 on both the front and back, providing a high level of neutral density.
This filter is mounted with SM2 threads, allowing it to be easily integrated into various optical systems. The current status of this item is "in stock", and more detailed information can be found on Thorlabs' official website at https://www.thorlabs.com/thorproduct.cfm?partnumber=NDUV2R13A.
