Blaze Wavelength

The wavelength of peak grating efficiency based upon the blaze angle. The maximum efficiency occurs when the incident angle from the blaze normal and diffracted rays from the blaze normal are equal (Littrow configuration). Using the grating equation, it is easy to determine the appropriate blaze angle for a specific peak efficiency (blaze wavelength) or determine the blaze wavelength from the blaze angle.
