Flat Top, Ultra-Narrow Bandpass Optical Filters Using Plasma Deposited Hard Oxide Coatings

Thin film optical filters with ultra-narrow bandwidth, high transmission and flat spectral profiles improve optical system performance for a variety of applications such as LIDAR, laser cleanup, and instrumentation. Alluxa’s new class of ultra-narrow filters are designed for applications such as laser clean up, LIDAR, telecommunications and instrumentation and offer the narrowest and “squarest” filter profiles in the visible and NIR as well as transmission levels that approach 100%.
