Coatings That Are Less Affected by Environmental Factors, Including Temperature and Humidity
Surface Roughness No Longer Limited by Coating
Coatings Covering Wavelengths Between 266-1600nm
Group Delay Dispersion (GDD) Control for Ultrafast Coatings
Edmund Optics® designs and manufactures optical coatings deposited using ion beam sputtering (IBS), a highly-repeatable coating technology ideal for high-reflectivity mirrors, ultrafast mirrors, and filters with sharp transitions.
Measuring High Reflectivity IBS Coatings Using Cavity Ring-Down (CRD) Loss Meters
State-of-the-Art Metrology for Highly-Reflective Optical Components
Highly-Sensitive Measurement of Total Loss in the Parts per Million
Signal Decay Rate Measured in Cavity Consisting of Test Optic and Reference Mirror
Figure 1: CRD loss meters produce a highly-sensitive loss measurement of signal decay rate, quantifying a component’s transmission, absorption, and scatter.
Figure 2: Loss measurements made using CRD are much more accurate for highly-reflective optics than direct transmission or reflection measurements made using a spectrophotometer.
