This filter is characterized by its circular shape, with a diameter of 41 mm and a thickness of 5 mm, making it suitable for a wide range of optical applications. The filter is made from UVFS MAL-1965 material, ensuring durability and high-quality performance.

The 59-166 features a neutral density coating on both the front and back, specifically the EDM 59-162 coating. This coating is designed to absorb a specific portion of the light spectrum, in this case, 400-700nm, without altering the color balance of the light passing through it. This makes it an ideal choice for applications where light intensity needs to be reduced without affecting the color composition.

The filter is designed in the shape of a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This design allows for a wide field of view and minimal distortion, making it suitable for a variety of optical systems.
