63-462 25 mm Dia. Hoya ND-25 Absorptive Neutral Density (OD 0.7) Color Filter

The 63-462 25 mm Dia. Hoya ND-25 Absorptive Neutral Density (OD 0.7) Color Filter is a high-quality optical component sourced from Edmund Optics. This filter is designed with a circular shape, featuring a diameter of 25 mm and a thickness of 3.1 mm, making it suitable for a wide range of optical applications.

The filter is made from UVFS Mal-1965 material, a unique glass compound known for its excellent optical properties. It is specifically designed to absorb light across the visible spectrum, with a peak wavelength of 588 nm. This makes it an ideal choice for applications that require light absorption, such as reducing light intensity or eliminating specific wavelengths.

The filter is coated with EDM 63-458 on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The coating also provides excellent environmental stability, ensuring the filter maintains its performance characteristics over time.

The 63-462 filter is shaped as a thin lens, which is beneficial for applications that require minimal optical path length distortion. This shape also reduces the risk of optical aberrations, ensuring the filter delivers high-quality, distortion-free optical performance.
