48-526 12.5 mm Dia. Hoya ND-25 Absorptive Neutral Density (OD 0.5) Color Filter

The 48-526 is a 12.5 mm diameter Circular Color Glass Filter, specifically designed for use in optical systems that require Neutral Density (ND) filtration. This filter is sourced from the reputable vendor, Edmund Optics, and boasts an OD (Optical Density) of 0.5, providing a reduction in light intensity of 75%.

The filter is made from UVFS (Ultraviolet Fused Silica) material, identified by the Mal-1965 material ID. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum, making it ideal for a wide range of optical applications.

The filter has a thickness of 2 mm and is designed to transmit light within the 400-700 nm wavelength range. This makes it suitable for use in systems that operate within the visible light spectrum.

The front and back surfaces of the filter are coated with the EDM 48-526 coating, which is specifically designed to enhance the filter's performance and durability. The filter's shape is that of a Thin Lens, further enhancing its utility in optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
