The ND510B is a circular, unmounted Neutral Density (ND) filter, manufactured by Thorlabs, with a diameter of 0.5 inches and a thickness of 1 millimeter. This filter is made of N-BK7 Schott glass, a high-quality material known for its excellent optical properties.
The ND510B filter features a front and back coating of THo ND10, a reflective coating that provides a neutral density of 1.0. This coating reduces the intensity of light entering the optical system without altering its color composition, making it an ideal choice for various applications where light intensity needs to be controlled.
The filter's geometry is designed in a thin lens shape, which not only contributes to its compactness but also minimizes optical aberrations. The ND510B is currently in stock and available for purchase through the Thorlabs website, as indicated by its valid weblink status.
