Frequently Asked Questions
The efficiency performance of the ruled plane gratings varies depending on the specific grating. The datasheet provides efficiency curves for three different gratings: 510 21; 300 l/mm; blaze 2 µm, 510 37; 75 l/mm; 5-16 µm, and 510 12; 600 l/mm; blaze 400 nm. These efficiency curves 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).
The custom master ruled gratings for CO2 lasers are optimized at 10.6 micron and made with a ruling density of 150 l/mm. The coating is gold and the substrate material is stainless steel with 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.
The blaze angle of the ruled plane gratings is given by the formula 2a sinα= kλB, where a is the groove spacing, k is the diffraction order (usually k=1) and λB is the blaze wavelength (in Littrow configuration). The blaze angle is indicated on page 35 of the datasheet.
Ruled plane gratings are high-precision replicas of ruled master gratings produced by HORIBA Jobin Yvon. They are used in various applications such as monochromators, spectrographs, Raman spectrometers, and beam isolation.
The dimensions of the high-precision replica gratings typically range from 25x25 mm up to 120x140 mm.
