AND-25C-70 25 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

The AND-25C-70 is a 25 mm diameter Optical Glass Neutral Density Filter, specifically designed for use in the visible light spectrum, between 400-700nm. This filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems.

The filter is manufactured by OptoSigma, a leading vendor in the optical industry, known for their high-quality, precision-engineered optical components. The filter is of the Absorptive Neutral Density type, which means it reduces the intensity of light equally across the visible spectrum, without altering the color balance.

The filter has a geometry defined by a 25mm diameter and a thickness of 2mm, making it suitable for a wide range of optical applications. The front and back surfaces of the filter are coated with 'opt and-70', a coating that enhances the filter's performance and durability.

The filter's shape is defined as a Thin Lens, which is a lens with a very small focal length compared to its diameter. This shape allows the filter to be used in various optical systems without causing significant distortion or aberration.

The filter is currently in stock and can be purchased directly from the vendor's website. More information about the filter, including pricing and availability, can be found at the provided weblink.
