OptoSigma's FND-50C02-0.1 is a 50 mm diameter, unmounted Neutral Density Filter, designed for use in the visible light spectrum, specifically between 400-700nm. This filter is made from N-BK7, a high-quality borosilicate glass manufactured by Schott, ensuring durability and reliability.

The filter features a reflective Neutral Density coating, denoted as 'opt fnd-0-1' on both the front and back surfaces. This coating is designed to reduce the intensity of light passing through the filter without altering its color balance, making it an ideal choice for applications requiring light control.
