Built using proprietary manufacturing processes and custom in-house metrology that result in ±1-nm thickness precision, these etalons lead the industry with superior free-spectral-range tolerances to as tight as ±0.001 GHz. They are supplied to leading OEM customers and researchers worldwide in the telecommunications, aerospace, laser research, and defense industries. With temperature tuning, solid etalons enable precise alignment to the telecommunications ITU grid without active alignment during packaging.
Multi-cavity etalons with flat-top filter functions are also available. They utilize our unique epoxy-free-bonding (CADB) technique for 100% optically transparent optical paths and zero bondline thickness.
