14NDF-40-1 12.7 mm Dia. Unmounted Absorptive Neutral Density Filter; OD 0.4 400-700nm

This is the 14NDF-40-1 Neutral Density Filter, a high-quality optical component manufactured by Standa. The filter is designed to reduce the intensity of incident light without altering its color composition, making it an essential tool in various optical applications.

The filter features a circular shape with a diameter of 12.7 mm and a thickness of 3 mm, ensuring a compact and robust design. It is made from UVFS material, specifically identified as MAL-1965, which guarantees durability and reliability.

The filter's primary function is achieved through its coating. Both the front and back surfaces are coated with Sta 14ndf-0.4, a specialized absorptive coating that provides a neutral density of 0.4 (OD 0.4) across the wavelength range of 400-700 nm. This broadband coverage makes the filter versatile and suitable for a wide range of applications.

The filter's shape is designed as a thin lens, which not only contributes to its compactness but also minimizes optical aberrations, ensuring optimal performance.
