ND2R30A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 3.0
The ND2R30A is a Neutral Density Filter with a diameter of 50 mm, manufactured by Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal tool for various optical applications.
The filter features a uniform optical density of 3.0, which signifies a 1000-fold reduction in light intensity. This high attenuation level is particularly beneficial in high-intensity lighting scenarios, such as laser applications or bright sunlight conditions, where it is crucial to prevent overexposure and potential damage to optical components.
The ND2R30A filter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and excellent transmission in the visible spectrum. The filter's thin lens shape and SM2-threaded mount ensure easy integration into existing optical systems.
