The model 74029 Grating Assembly is designed for installation into the Oriel Cornerstone 130 family of monochromators. This 30 x 30 mm grating comes bonded to a mount, allowing it to be installed inside the instrument. The grating efficiency exceeds 20% over its entire operating range, with a peak efficiency of 90% at its blaze wavelength.
This Grating Assembly may be installed in the field, after which the grating must be aligned and calibrated. However, it is suggested to return the instrument to Newport for grating installation and calibration. During recalibration, the instrument is thoroughly assessed to ensure optimal performance and routine maintenance services are performed. The monochromator is returned with a Certificate of Calibration, guaranteeing the instrument meets or exceeds it specifications.
