FND-50C02-50 50 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm
The FND-50C02-50 is a high-quality Neutral Density Filter, unmounted and with a 50 mm diameter. This filter is designed for use in the visible spectrum, specifically between 400 and 700 nanometers. The filter is made from N-BK7 Schott, a well-regarded optical glass known for its excellent transmittance and low auto-fluorescence.
The filter features a thickness of 2mm, which is optimal for maintaining the integrity of the optical path while minimizing unwanted reflections and aberrations. The front and back surfaces of the filter are coated with Opt FND-50, a reflective coating specifically designed for Neutral Density Filters. This coating enhances the filter's performance by reducing surface reflections and improving overall light transmission.
The filter's shape is that of a thin lens, which is beneficial for applications where space is a constraint. The filter is sourced from OptoSigma, a reputable vendor known for their high-quality optical components. The filter is currently in stock and available for immediate purchase through their website.
