13-083 12.5 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.5 425-675nm
This is the 13-083 Hoya Neutral Density Filter, a high-quality optical component designed for a wide range of applications. The filter boasts a 12.5 mm diameter and a thickness of 2 mm, making it a compact yet robust solution for your optical needs.
The filter is manufactured by Edmund Optics, a leading vendor known for its extensive catalog of optical elements. The filter is of the Neutral Density type, specifically an Absorptive Neutral Density Filter, which means it reduces the intensity of light without altering its color. This is achieved through a unique coating on both the front and back surfaces, identified as 'edm 13-083'.
The filter's wavelength is 588 nm, and it is designed to operate within the visible light spectrum, specifically between 425-675 nm. The Neutral Density value is 0.5, often referred to as OD (Optical Density) 0.5. This value indicates the filter's ability to reduce light intensity by half.
The filter's base shape is circular, and it features a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation. The filter is currently in stock and available for purchase through the provided weblink.
