13-098 25 mm Dia. Hoya ND-50 Absorptive Neutral Density Filter; OD 0.3 425-675nm

This is the 13-098 25 mm Dia. Hoya ND-50 Absorptive Neutral Density Filter, a high-quality optical component designed for a wide range of applications. Sourced from the reputable vendor Edmund Optics, this filter is part of their extensive catalog, which includes a variety of optical elements from different manufacturers worldwide.

The filter is a Neutral Density type, specifically designed to reduce the intensity of light without altering its color composition. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, cinematography, and scientific research. The absorptive nature of this filter ensures that it maintains a high level of optical quality, minimizing any potential distortions or aberrations.

The filter has a circular shape with a diameter of 25 mm and a thickness of 2.5 mm, making it compatible with many optical systems. It is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter is coated on both sides with EDM 13-081, a coating that enhances its performance and durability.

The wavelength of this filter is 588 nm, and it is designed to operate in the visible light spectrum, specifically between 425-675 nm. The filter has an Optical Density (OD) of 0.3, which corresponds to a reduction of 20% in light intensity. This makes it a medium-light reduction filter, suitable for situations where a significant but not total reduction of light is required.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information, you can visit the provided weblink.
