AND-40C-05 40 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm
OptoSigma's AND-40C-05 is a high-quality Neutral Density Filter, designed for use in the visible light spectrum, specifically between 400-700nm. This filter is unmounted, offering flexibility for integration into various optical systems.
The filter boasts a circular shape with a diameter of 40mm and a thickness of 2mm, making it a versatile choice for many applications. It is made from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability.
The filter's coating is another notable feature. Both the front and back are coated with Opt AND-05, a specialized coating that enhances the filter's performance and longevity. This coating contributes to the filter's overall neutral density, ensuring consistent light absorption across the visible spectrum.
The filter's geometry is described as a Thin Lens, suggesting a design that minimizes optical distortion and maintains the integrity of the light path. This feature is particularly beneficial in precision optical systems where distortion must be kept to a minimum.
