FND-50C02-10 50 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

OptoSigma's FND-50C02-10 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, known for its excellent optical properties and durability.

The filter features a thickness of 2mm, which is optimal for maintaining the integrity of the light path while minimizing unwanted reflections and dispersion. The front and back surfaces of the filter are coated with Opt FND-10, a reflective neutral density coating that further reduces the amount of light passing through the filter without altering the color balance.

This filter is shaped as a thin lens, making it suitable for use in various optical systems where a flat filter may cause unwanted reflections or distortions. The unmounted design allows for easy integration into existing setups and provides flexibility in choosing the right mount for your specific application.
