WebTransmission gratings offer low polarization sensitivity as opposed to reflection gratings because incident light is not reflected by a mirror coating such as aluminum. Since light is transmitted through the grating, transmission gratings can be used in compact, in-line configurations. They are ideal for use in monochromators and spectrometers. WebThe highest angle of diffraction achievable is 90 degrees. The lowest order of diffraction is 1. Plugging these values into the grating equation yields λ = 2d. which is the diffraction wavelength limit for any grating. A special case occurs when the angle of incidence i is equal to the angle of diffraction i’.
