AND-40C-10 40 mm Dia. Optical Glass Unmounted Visible Absorptive Neutral Density Filter 400-700nm

OptoSigma's AND-40C-10 is a high-quality Neutral Density Filter, designed for use in the visible light spectrum, specifically between 400-700nm. This unmounted filter, with a diameter of 40mm and a thickness of 2mm, is a circular component made of optical glass, featuring a UVFS MAL-1965 material ID.

The filter boasts a coating on both the front and back, specifically 'opt and-10', which is designed to absorb light evenly across the visible spectrum, thereby reducing the intensity of the light passing through it. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, cinematography, or scientific research.

The filter's thin lens shape ensures minimal distortion, making it suitable for use in precision optical systems. The filter is currently in stock and available for purchase through the OptoSigma website, as indicated by its 'Valid - in stock' weblink status.
