| SPECTRA AR Coating | |
SPECTRA
AR
is a cold process, i.e. the substrates are not heated up during
the coating procedure. An IPC (ion pre-cleaning) stage is followed
by the deposit of the broadband anti-reflection coating and the
deposit of the water-repellent layer respectively.
SPECTRA AR is a basic Broadband AR Coating for all common substrate materials for example mineral glass and for customer’s hard coated lenses i.e. CR39, PC, and High Index Materials and Transition lenses. |
