The MAN-25-5 is a Neutral Density Filter, specifically an Absorptive Neutral Density Filter, designed for use in the visible light spectrum (400-700nm). This filter is manufactured by OptoSigma, a leading vendor in the optical industry, and is available for purchase through their website.
The filter has a circular shape with a diameter of 25mm and a thickness of 2mm, making it a compact and versatile option for various optical applications. The base shape of the filter is a Thin Lens, which is designed to minimize optical aberrations and distortions.
The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with "opt and-05", which is a type of anti-reflective coating. This coating reduces unwanted reflections and increases the overall transmittance of the filter, enhancing its performance in various lighting conditions.
The material ID of the filter is "uvfs mal- 1965", which provides information about the specific type of optical glass used in its construction. This information can be crucial for users who need to match the filter with other optical components in their system.
