FND-50C02-1 50 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm
The FND-50C02-1 is a high-quality Neutral Density Filter, unmounted with a 50 mm diameter, manufactured by OptoSigma. This filter is designed for use in the visible spectrum, specifically between 400-700nm, making it suitable for a wide range of optical applications.
The filter is made from N-BK7 Schott, a well-regarded optical glass known for its excellent transmittance and low auto-fluorescence. The N-BK7 Schott material ensures high-quality performance and durability. The filter's geometry includes a diameter of 50mm and a thickness of 2mm, providing a robust and compact design.
The FND-50C02-1 features a reflective coating, Opt FND-1, on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission. The coating also provides a neutral density, which reduces the amount of light passing through the filter without altering its color balance.
The filter's shape is a thin lens, which is beneficial for applications where space is limited or weight needs to be minimized. The filter is currently in stock and available for immediate purchase through the provided weblink.
