The NDUV03B 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 renowned vendor in the optical industry. The filter is made of UVFS material, specifically identified as "UVFS mal- 1965".
The NDUV03B filter is designed to reduce the intensity of incident light without altering its color composition. This is achieved through the application of a front and back coating of "tho nduv od03", which provides a Neutral Density of 0.3 (OD 0.3).
The filter's geometry is shaped in a Thin Lens design, which is ideal for applications that require minimal optical interference. The NDUV03B is currently in stock and available for immediate purchase through the vendor's website, with the link provided in the item data.
