65-016 75 mm Diameter Mounted OD 0.3 Absorptive Neutral Density Filter; t=5 mm 400-700nm

The 65-016 is a Neutral Density Filter, a type of optical component that reduces the intensity of light without altering its color composition, making it ideal for applications requiring light level adjustments. This particular model, sourced from Edmund Optics, boasts a 75 mm diameter and a thickness of 5 mm, offering a substantial surface area while maintaining a manageable profile.

The filter's material ID, UVFS MAL-1965, suggests its composition, although specifics are not provided in the item data. The wavelength of 588 nm indicates the filter's optimal performance range, although it is designed to operate within the broader spectrum of 400-700 nm.

The coating on both the front and back surfaces of the filter is EDm 59-162, which likely contributes to its absorptive properties. The filter's shape is described as a Thin Lens, implying a specific curvature designed to focus or disperse light.
