Frequently Asked Questions
The typical efficiency performance of ruled plane gratings can be found on the datasheet. Efficiency curves are provided for different gratings, including 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).
Custom master ruled gratings optimized for CO2 lasers are made of stainless steel substrate material with a 25 mm diameter on 25x25 mm. The ruling density is 150 l/mm, and the coating is gold. The absolute efficiency is higher than 95% for TM polarization over 9 to 11 µm wavelength range.
The blaze angle (α) 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 can be found 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 applications such as monochromators, spectrographs, Raman spectrometers, spectroscopy, and beam isolation.
The dimensions of high-precision replica gratings typically range from 25x25 mm up to 120x140 mm.
