The MFND-30-20 is a Neutral Density Filter, specifically designed for use in the visible light spectrum, with a wavelength of 550nm. This filter is manufactured by OptoSigma, a leading vendor in the optical industry, and is available for purchase on their official website. The catalog number for this product is MFND-30-20.

This filter is mounted and features a circular design with a diameter of 30mm and a thickness of 2mm. The material used for the filter is N-BK7, a type of borosilicate glass manufactured by Schott AG, which is known for its excellent optical properties and durability.

The filter is coated on both the front and back with the Opt FND-20 coating.
