48-525 12.5 mm Dia. Hoya ND-40 Absorptive Neutral Density (OD 0.4) Color Filter

The 48-525 is a 12.5 mm diameter circular color filter, specifically designed for use in optical systems. This filter is manufactured by Hoya, a renowned name in the optical industry, and sourced from Edmund Optics, a trusted global supplier of optical components. The filter is designed to provide a neutral density of 0.4 (ND-40), which is achieved through an absorptive process, making it ideal for applications where light intensity needs to be reduced without altering the color balance.

The filter has a base shape of a circle, with a diameter of 12.5 mm and a thickness of 2.5 mm. This makes it compatible with a wide range of optical systems. The filter is made from UVFS material, identified by the Mal-1965 material ID, ensuring durability and reliability.

The filter features a thin lens shape, which helps to minimize optical aberrations. The front and back surfaces of the filter are coated with the EDM 48-525 coating, which further enhances its performance and longevity.

The filter is designed to operate within the wavelength range of 400-700 nm, with a peak wavelength of 588 nm. This makes it suitable for a wide range of applications, including photography, beam shaping, and laser applications.
