The NDUV530B is a circular Neutral Density Filter, unmounted, with a diameter of 0.5 inches and a thickness of 1 millimeter. This filter is sourced from Thorlabs, a renowned vendor in the optical industry, and is part of their UVFS reflective series, specifically identified by the material ID "uvfs mal- 1965".
The NDUV530B is designed to operate at a wavelength of 300 nanometers. It features a coating on both the front and back surfaces, specifically the "tho nduv od3" coating, which is a unique offering from Thorlabs. This coating is a part of their Neutral Density UV filters, which are specifically designed for UV applications.
The filter's shape is described as a Thin Lens, which is a type of optical component designed to focus light. This particular filter, however, is unmounted, meaning it does not come with any housing or mounting mechanism. This allows for flexibility in integration but requires additional considerations for safe and secure mounting.
The filter's status is "in stock" as per the vendor's website, and the link to the product page is provided for further reference.
