FND-30C02-5 30 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

The FND-30C02-5 is a 30 mm diameter, unmounted Neutral Density Filter, boasting a thickness of 2mm and designed for use within the visible light spectrum of 400-700nm. This filter is fabricated using N-BK7, a high-grade borosilicate glass from Schott, renowned for its excellent optical properties and durability.

This particular filter is coated with OptoSigma's proprietary FND-5 coating on both the front and back surfaces. This coating is specifically designed to provide high reflectivity within the visible light spectrum, making it an ideal choice for applications where precise light control and reflection are critical.

The filter's geometry, featuring a thin lens shape, ensures minimal distortion and maintains the integrity of the light path. The unmounted design provides flexibility, allowing for easy integration into various optical systems.
