Flat Field and Imaging Gratings - Type IV
HORIBA Scientific produces a wide range of holographic master gratings from which high precision replicas are manufactured.
Type IV aberration-corrected flat field and imaging gratings are designed to focus a spectrum onto a plane surface, making them ideal for use with linear or 2-D array detectors.
These gratings are produced with grooves that are neither equis-paced nor parallel, and are computer optimized to form near-perfect images of the entrance slit on the detector plane.
