Ultra-Low Absorption Coatings Line of thin Film Coatings - IBS
BFi OPTiLAS, pan-European partner of Precision Photonics Corporation (PPC), is pleased to announce the availability of its ultra-low absorption line of thin film coatings.
Enabled by advanced in-house metrology and expertise in ion beam sputtered (IBS) deposition, we are able to routinely deliver anti-reflection (AR) coatings with losses less than 0.5ppm, and high-reflection (HR) coatings with losses less than 2ppm.
This unique capability is based on photothermal common path interferometry, and when combined with proprietary calibration methods, results in measurement sensitivity of less than 0.1ppm for optical materials like fused silica.
Measurement services to customers wishing to measure absorption in their own coatings or substrates is also available including two dimensional mapping of surfaces.
The combination of extreme durability, high reliability, precision spectral control, and high laser damage threshold makes ion beam sputtering the coating method of choice for high power laser applications and low loss optics. Those unique performance should be of major interest to customers using these optics in ‘world leading’ 10kW class laser systems.
