Standard Concave Gratings (Low Stray Light and High Efficiency)
for Constant Deviation Monochromators
Concave gratings have the advantage of setting up a spectroscopic system without any imaging optics like concave mirrors.
Toroidal Gratings (Higher light collection efficiency)
Toroidal gratings are more astigmatic than conventional aberration-corrected concave gratings.
It has a higher light collection efficiency than a concave grating, making it suitable for applications that require faint light detection.
