The 63-400 is a Neutral Density Filter with a 12.5 mm diameter and a thickness of 1.5 mm. This filter, sourced from Edmund Optics, is designed to reduce the intensity of incident light without altering its color composition. It boasts a non-reflective coating on both the front and back surfaces, minimizing unwanted reflections and ensuring optimal performance.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It is designed to operate at a wavelength of 1064 nm, making it suitable for a wide range of applications that require light attenuation in the near-infrared spectrum.
The 63-400 filter features a thin lens shape, which is beneficial for applications where space is a constraint. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
