Frequently Asked Questions

HORIBA Jobin Yvon offers custom master ruled gratings optimized for CO2 lasers. The ruling density is 150 l/mm, and the coating is gold. The substrate material is stainless steel, and the substrate dimension is 25 mm diameter on 25x25 mm. The absolute efficiency is higher than 95% for TM polarization over 9 to 11 µm wavelength range. Customers can also request different substrate materials and coatings.

The efficiency performance of the ruled plane gratings varies depending on the type. HORIBA Jobin Yvon provides absolute theoretical efficiency curves for reference. The efficiency curves are calculated using rigorous electromagnetic theory, taking into account the true groove profiles of manufactured gratings measured with an atomic force microscope (AFM).

HORIBA Jobin Yvon is ISO9001:2000 certified and offers complete customer service, including expert technical advice for optimizing system configurations to meet customers’ needs. Their well-staffed departments are committed to customer satisfaction and product quality.

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, spectroscopy, and beam isolation.

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