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 equi-spaced nor parallel, and are computer optimized to form near-perfect images of the entrance slit on the detector plane.
Such gratings are available with ion etched profile for extremely high efficiency (fluorescence) and with sinusoidal profile for applications requesting less low stray light (absorbance).
