AND-30C-20 30 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm
The AND-30C-20 is a high-quality Neutral Density Filter, offered by the renowned optical components manufacturer, OptoSigma. This filter is designed for use in the visible light spectrum, specifically absorbing light within the 400-700nm range.
The filter is circular in shape, with a diameter of 30mm, making it suitable for a wide range of optical applications. It has a thickness of 2mm, which is thin enough to minimize any potential distortions, yet sturdy enough to ensure durability.
The filter's coating is another notable feature. Both the front and back surfaces are coated with OptoSigma's AND-20 coating, which is designed to provide superior neutral density performance. This coating ensures that the filter absorbs light evenly across the visible spectrum, resulting in accurate and consistent color reproduction.
The filter is unmounted, providing users with the flexibility to mount it in a way that best suits their specific application. It is made from UVFS Mal-1965, a high-quality optical glass material known for its excellent optical properties and durability.
