FND-30C02-10 30 mm Dia. Unmounted N-BK7 Visible Reflective Neutral Density Filter; t=2mm 400-700nm

The FND-30C02-10 is a high-quality Neutral Density Filter, unmounted and with a 30 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 ideal for applications requiring a balance between durability and minimal optical path distortion. The front and back surfaces of the filter are coated with the Opt FND-10 coating, a reflective neutral density coating that provides a uniform attenuation of light across the visible spectrum. This coating is designed to maintain the neutrality of the transmitted light, ensuring that colors are not shifted or distorted.

The filter's shape is that of a thin lens, making it suitable for use in a wide range of optical systems. The FND-30C02-10 is currently in stock and available for purchase through the vendor, OptoSigma.
