As technology advances, data communications require greater transmission rates. as such, Etalons and optical filters are becoming increasingly important. In this article Iridian discusses the usage of their filters and etalons in data applications.
HELIX™ Spectral Analysis System accurately measures the highest-performance optical filters. The HELIX Spectral Analysis System has redefined measurement capabilities of high performance thin-film optical filters. HELIX is an instrument designed and developed by Alluxa Engineering staff to address the limitations of most commercially available spectrophotometers. The system’s capabilities are four-fold: it is able to track filter edges to OD7 (-70 dB), evaluate blocking to OD9 (-90 dB), resolve edges as steep as 0.4% relative to edge wavelength from 90% transmission to OD7, and resolve pa...
