FNG0425 25 mm Dia. Absorptive Glass Neutral Density Filter 546nm

The FNG0425 is a 25 mm diameter Neutral Density Filter, specifically designed for use in optical systems that require a 546nm wavelength. Sourced from Knight Optical, a reputable vendor in the optical industry, this filter is a high-quality component that ensures accurate and reliable performance.

The filter is of the Neutral Density type, which means it reduces the intensity of light without altering its color. This is particularly useful in applications where controlling light intensity is crucial, such as in photography, cinematography, and scientific research. The FNG0425 is made from UVFS MAL-1965 glass, a material known for its excellent optical properties and durability.

The FNG0425 has a circular shape, a standard in optical systems due to its ease of alignment and integration. It features a thickness of 3.2mm, providing robustness and stability in the setup. The filter also boasts a Thin Lens shape, which minimizes optical aberrations and distortions, ensuring the highest quality image output.

The front and back surfaces of the filter are coated with KNI FNG04, a coating that enhances the filter's performance and longevity. This coating helps to reduce reflections, increase transmission, and protect the filter from environmental hazards.
