AND-50C-20 50 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-50C-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 50mm and a thickness of 2mm, making it compatible with a wide range of optical systems. It is made from UVFS MAL-1965 optical glass, a material known for its excellent optical properties and durability.

The filter features absorptive coatings on both the front and back surfaces, identified as 'opt and-20'. This coating is designed to provide a consistent and uniform attenuation of light across the entire spectral range of the filter. The coating also helps to protect the optical surface of the filter from scratches and other forms of damage.

The filter has a 'Thin Lens' shape, which is designed to minimize optical aberrations and distortions. This makes it an ideal choice for applications that require high-precision optical performance.

The filter is currently in stock and available for purchase through the OptoSigma website. For more information, please refer to the provided weblink.
