AND-40S-001 40 x 40 mm Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm
The AND-40S-001 is a 40 x 40 mm Neutral Density Filter, specifically designed for use in the visible light spectrum, between 400-700nm. This filter is produced by OptoSigma, a leading vendor in the optical industry, known for their high-quality, precision-engineered products.
The filter is of the Absorptive type, meaning it reduces the intensity of light by absorbing it, rather than reflecting or scattering it. This absorption is uniform across the visible spectrum, ensuring accurate color representation in the filtered light.
The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems in a way that best suits their specific needs. It features a thin lens shape, with dimensions of 40mm in both height and width, and a thickness of 2mm.
The front and back surfaces of the filter are coated with the OPT AND-001 coating, which provides additional protection and enhances the filter's performance. The catalog number for this item is AND-40S-001, and it can be found on the OptoSigma website, where it is currently in stock.
