Coating technologies used at Melles Griot: E-Beam Thermal Evaporation, Ion Assisted Deposition (IAD), and Advanced Plasma Source (APS) Deposition

Melles Griot designs and manufactures a large variety of custom coatings in low to high volume quantities ranging from DUV (193 nm) to Mid IR (3200 nm). All Melles Griot custom coatings offer an excellent combination of high performance, shift-free spectra, high laser damage and low absorption. Our anti-reflection coatings with R<0.03% and high-reflection mirrors with R>99.95% are ideal for multi-wavelength and very broadband and high angle of incidence applications.
