ND2R03A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 0.3
The ND2R03A 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 0.3, which corresponds to a 20% transmission of light.
The filter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and durability. It has a thickness of 2 mm, which contributes to its robustness and overall performance. The front and back surfaces of the filter are coated with THo ND03, a specialized coating that enhances the filter's light reduction capabilities.
The ND2R03A filter is designed with a Thin Lens shape, featuring an SM2-threaded mount for easy integration into existing optical systems. The filter's geometry is carefully crafted to minimize optical aberrations and ensure high-quality performance.
