The angle between the slits remains constant as the grating is rotated to scan wavelengths. Ruled concave gratings are usually blazed as a natural consequence of the ruling process, and some holographic gratings can be blazed by ion milling. Please contact us which grating has the best performance for your specifications. The Richardson Grating Laboratory can design a custom concave grating to best suit your specifications.
