NDUV504B Dia. 0.5 in Unmounted UVFS Reflective ND Filter; OD 0.4
The NDUV504B 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 reputable vendor in the optical industry, and is part of their UVFS series, specifically identified as UVFS MAL-1965.
The NDUV504B is designed with a UVFS reflective coating, both on the front and back, boasting an Optical Density (OD) of 0.4. This specific OD value indicates that the filter reduces the light intensity by a factor of 1.6, providing a subtle yet effective reduction in light transmission.
The filter's geometry is that of a thin lens, and it is compatible with wavelengths as short as 300 nanometers. This makes it suitable for applications that involve ultraviolet light.
