NDUV520A Dia. 0.5 in SM05-Threaded Mount; UVFS Reflective ND Filter; OD 2.0
The NDUV520A is a Neutral Density Filter from Thorlabs, designed with a circular shape and a diameter of 0.5 inches. It features a UVFS reflective coating on both the front and back, offering an Optical Density (OD) of 2.0. This filter is specifically designed for use with UV light, with a wavelength of 300 nm.
The NDUV520A is mounted with an SM05 thread, a common thread size for many Thorlabs components. This mounting system ensures a secure and stable fit, allowing for easy integration into existing optical systems. The filter has a thickness of 1 mm, making it a thin lens, which can be beneficial in reducing the overall weight and size of the optical system.
The UVFS reflective coating on the NDUV520A is a proprietary coating developed by Thorlabs. It provides excellent neutral density performance, ensuring minimal color shift across the UV spectrum. This makes it an ideal choice for applications that require precise control over UV light intensity.
