Frequently Asked Questions

The efficiency curves for ruled plane gratings are absolute theoretical efficiencies, calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM). These curves are for reference only and do not indicate grating specifications.

The custom master ruled gratings for CO2 lasers are optimized at 10.6 micron for CO2 lasers with a ruling density of 150 l/mm, gold coating, stainless steel substrate material, and a substrate dimension of 25 mm diameter on 25x25 mm. The absolute efficiency is higher than 95% for TM polarization over 9 to 11 µm wavelength range.
