As a general approximation, for blazed gratings the strength of a signal is reduced by 50% at two-thirds the blaze wavelength, andtimes the blaze wavelength.;Holographic diffraction grating film comes in two different groove spacing options: 12,700 lines/inch (500 lines/mm) and 25,400 lines/inch (1000 lines/mm). By increasing the number of grooves per unit area, the angular dispersion of diffraction orders will be increased.

Brand New.out of 5 stars. 1 product rating - Diffraction Grating sheet 1,000 lines/mm Linear 1ft long x 6 Inches Wide.;Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating's surface. Diffraction Gratings can be either transmissive or reflective. As light transmits through or reflects off a Grating, the grooves cause the light to diffract, dispersing the light into its component wavelengths.
