Bach to Supply NIRPS Gratings

Custom diffraction grating manufacturer Bach Research Corp. has been awarded a contract by the NIRPS (Near Infrared Planet Searcher) consortium to manufacture and deliver a custom R4 echelle grating and spares that will be used in the NIRPS instrument.

NIRPS is a high-resolution, near-infrared, fiber-fed and cross-dispersed echelle spectrograph designed for accurate radial-velocity measurements. The instrument is set to be installed on the 3.6-m European Southern Observatory telescope at the La Silla Observatory in Chile. The R4 echelle grating is 90 × 320 mm with a blaze angle of 76°.

The consortium consists of the Institute for Research on Exoplanets (iREx) at the University of Montréal and the Observatory of Geneva at the University of Geneva.

Bach Research is a manufacturer of custom diffraction gratings and optical components for OEM, aerospace research, defense, astronomy and spaceflight instrumentation.
