65-022 57 mm Dia. Mounted OD 0.9 Absorptive Neutral Density Filter; t=5 mm 400-700nm

The 65-022 is a Neutral Density Filter, a type of optical component designed to reduce the intensity of incident light without altering its color composition. This particular model, sourced from Edmund Optics, boasts a 57 mm diameter and a thickness of 5 mm, making it suitable for a wide range of optical applications.

The filter features an absorptive coating, denoted as EDM 59-172 on both the front and back surfaces. This coating is specifically designed to absorb a broad spectrum of light, from 400 to 700 nm, ensuring consistent attenuation across the visible light range. The absorptive nature of this coating also means that it does not introduce any phase shift, making it an ideal choice for applications where phase distortion cannot be tolerated.

The 65-022 is mounted in a Thin Lens shape, which is a common configuration for optical filters. This shape ensures easy integration into existing optical systems, and the thin profile helps minimize any potential vignetting effects.
