Alluxa, an emerging leader in next generation optical filters is pleased to announce ultra-flat dichroic and polychroic filters with very high levels of in band transmission.
These filters are unique because they achieve flatness by eliminating the high stresses of as-deposited traditional ion-based coating process such as Ion Beam Sputtering (IBS) and Ion Assisted Deposition (IAD). Alluxa’s new technique uses a novel plasma hard coating process that produces low-loss, fully dense dielectric films with essentially net zero stress on the primary coated side. Because of this new technology, the films do not require the lengthy additional coating time of industry standard backside compensation or require the use of very thick and expensive substrates.
Typical uses for Ultra-flat, thin dichroics are in imaging and laser based applications like confocal microscopy, DNA sequencing, and communications.
