FNM0513 12.5 mm Dia. Metallic Neutral Density Filter 546nm

The FNM0513 is a Neutral Density Filter with a diameter of 12.5 mm and a thickness of 2 mm, sourced from the renowned optical components vendor, Knight Optical. This filter is designed to reduce the intensity of all wavelengths of light equally, making it an ideal choice for applications that require a consistent reduction in light intensity without altering the color balance.

The filter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior chemical resistance. This material ensures the filter provides reliable and consistent performance, even under harsh environmental conditions.

The FNM0513 features a thin lens shape, which not only minimizes the weight and thickness of the filter but also reduces the risk of optical aberrations. The front and back surfaces of the filter are coated with the KNI FNM05 coating, which enhances the filter's durability and resistance to scratches, environmental contaminants, and other potential damage sources.

This filter is currently in stock and available for immediate purchase through the Knight Optical website. The item data also includes a valid weblink for easy access to the product page, where you can find more detailed specifications, pricing information, and purchasing options.
