Chroma sputtered coatings
Each filter is made on a single substrate of high-grade glass with very durable hard sputtered coatings, so no lamination is needed. The coatings withstand humidity and temperature extremes and are spectrally precise in centre wavelength and bandpass. The primary coating is on the front face and an anti-reflection coating on the back to prevent ghosting and maximise transmission.
