FNG3020 20 x 25 mm Absorptive Glass Neutral Density Filter 546nm

The FNG3020 is a Neutral Density Filter, specifically designed for use in optical systems that require precise light control. This filter, sourced from Knight Optical, is a 20 x 25 mm rectangular component with a thickness of 2.9 mm, making it an ideal choice for applications that require a thin, yet robust optical element.

The filter is made from UVFS Mal-1965, a high-quality glass material known for its excellent optical properties. This material ensures the filter maintains its optical performance even under demanding conditions. The filter's neutral density characteristic, achieved through a specialized coating on both the front and back surfaces (kni fng30), provides a uniform attenuation of light across the entire visible spectrum, with a peak wavelength of 546nm.

This filter is currently in stock and available for immediate purchase through the vendor's website, as indicated by its 'Valid - in stock' weblink status. The FNG3020, with its precise specifications and high-quality construction, is a reliable choice for a wide range of optical applications.
