NDUV2R04B Dia. 50 mm Unmounted UVFS Reflective ND Filter; OD 0.4
The NDUV2R04B is a Neutral Density Filter with a diameter of 50 mm, manufactured by Thorlabs. This unmounted filter is designed with a thin lens shape and a thickness of 2 mm, making it a compact and convenient option for various optical applications.
The filter features a UVFS material ID, specifically mal- 1965, and is coated with THo NDUV OD04 on both the front and back surfaces. This coating is designed to provide a neutral density of 0.4, which is equivalent to an optical density of 0.4. This means that the filter reduces the intensity of incident light by a factor of 2.512 (approximately), regardless of its wavelength within the specified range.
The filter's geometry and coating make it suitable for use with wavelengths of 300 nm. This can be beneficial in applications where control of light intensity is required, such as in imaging, spectroscopy, or beam manipulation.
