Multiline coatings

Even extraordinary wishes can be fulfilled, only the sky is the limit...

Sometimes it is necessary to use different filter coatings on a pair of substrates or on the front and rear surface of an optic.

The example above has a broadband long wave pass coated on the front and a gain flattener on the rear surface for superposition of the deuterium and halogen lamp spectra. As shown, the measured reflection (red line) complies with the computed values (black line). This proofs the high precision of the IBS-coating technique.

All values are given for standard coatings. Customized coatings available for all types.
