AND-50S-30 50 x 50 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm
OptoSigma's AND-50S-30 is a high-quality Neutral Density Filter, designed to minimize the effects of light intensity without altering color balance. This filter is unmounted, making it a versatile option for various optical applications.
The filter boasts a base shape of 50 x 50 mm, providing a substantial surface area for light transmission. It is constructed from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability. The filter's thickness is 2 mm, ensuring rigidity and resistance to distortion.
The coating of the filter is another notable feature. Both the front and back surfaces are coated with Opt AND-30, a specialized absorptive coating that enhances the filter's performance in the visible light spectrum (400-700nm). This coating reduces light transmission by 30%, providing the necessary neutral density for various applications.
The filter's shape is thin lens, which is beneficial for applications where minimal thickness is required. This feature also reduces the risk of vignetting, ensuring a clear and consistent image across the entire field of view.
