NDUV30B Dia. 25 mm Unmounted UVFS Reflective ND Filter; OD 3.0
The NDUV30B is a circular Neutral Density Filter, unmounted, with a 25 mm diameter and a thickness of 1 mm. 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 NDUV30B is designed to provide neutral density, which means it reduces the amount of light entering the optical path without altering the color composition. This filter has a wavelength of 300 nm, making it suitable for applications that require significant light reduction at this specific wavelength.
The filter features a coating on both the front and back surfaces, denoted as "tho nduv od3". This coating is likely a part of Thorlabs' proprietary technology, contributing to the filter's overall performance and functionality.
The NDUV30B filter has a shape described as "Thin Lens", indicating a specific design or manufacturing process that may offer advantages in certain applications. However, without additional information, it's challenging to provide a detailed explanation of this characteristic.
