Laser and LED-based optical systems depend on optical filters and mirrors to route, combine, separate, and purify light as a function of wavelength and/or polarization, often at high intensity. Filter efficiency plays a large role in overall system performance, and can mean the difference between an experiment or product design that is successful and one that is not.
Ion Beam Sputtered (IBS) optical filters allow highly discriminating filter shapes to be created with high transmission and/or reflection efficiency, eliminating extraneous light from a system, or ensuring every possible photon is routed to a sample or detector. It also yields environmentally stable coatings with very high laser damage threshold, maximizing system lifetimes in industry and enabling cutting-edge research in the lab.
