The 14-099 is a 25 mm diameter, 1mm thick Neutral Density (ND) Color Filter, manufactured by SCHOTT and sourced from Edmund Optics. This filter is designed for use in the 400-700nm wavelength range, making it suitable for a wide range of optical applications.
The filter features a Gray Glass material ID, specifically UVFS MAL-1965, and is cut on at 400nm and cut off at 700nm. It has a circular base shape and a thin lens shape, which is ideal for applications where space is a constraint. The filter's physical data indicates that it is designed to absorb light across the entire spectrum, providing a neutral color balance.
The 14-099 filter is coated on both the front and back with EDM 14-098, a coating that enhances its performance and durability. The filter's vendor, Edmund Optics, lists it as in stock on their website, with a direct weblink provided for easy access and purchase.
