ND505B Dia. 0.5 in Unmounted Reflective ND Filter; Optical Density 0.5
The ND505B is a circular neutral density filter with a diameter of 0.5 inches, sourced from the reputable vendor Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an essential tool for various optical applications.
The filter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It has a thickness of 1 millimeter, providing sufficient durability while maintaining minimal optical distortion. The ND505B is coated with THo ND05 on both the front and back surfaces, which contributes to its neutral density properties.
The ND505B filter features a thin lens shape, which minimizes vignetting and ensures a consistent optical density across the entire aperture. This makes it suitable for use in systems where a uniform reduction of light intensity is required.
The filter is currently in stock and available for purchase through the provided web link. With its reliable performance and versatile applications, the ND505B is an excellent choice for those seeking a high-quality, unmounted reflective neutral density filter.
