Anti-reflection coatings

In partnership with Artemis Optical,  anti-reflection coating of GLS chalcogenide glass has been demonstrated.  This reduces reflections from GLS glass surfaces to <1%, significantly lower than the ~28% reflection from the uncoated glass that is a result of its high … Continue reading
