Didyium Filters

Schott BG20 Didymium Filters are optical calibration filters made from high-quality optical glass with an interference coating that blocks unwanted light.

They are designed to reduce the transmission of wavelengths below 500 nm and increase the transmission of longer wavelengths, making them ideal for enhancing the contrast of red and orange features in images. These filters have a unique blend of rare earth elements and are ideal for use in photography and other optical applications where the separation of colours is important. Schott BG20 Didymium Filters are highly durable, scratch-resistant, and have excellent thermal stability.
