Frequently Asked Questions

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

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).

Ruled plane gratings are used in monochromators, spectrographs, Raman spectrometers, spectroscopy, and beam isolation.

HORIBA Jobin Yvon is ISO9001:2000 certified and committed to customer satisfaction and product quality.

The dimensions of high-precision replica gratings typically range from 25x25 mm up to 120x140 mm.
