Diffraction grating: Definition, formula and applications

“The diffraction grating is a useful device for analyzing light consists of a large number of equally spaced parallel slits.”Its working principle is based on the phenomenon of space between lines act as slits and these slits diffract the light waves thereby producing a large number of beams which interfere in such a way to produce spectra.

Diffraction grating - Wikipedia

Diffraction grating - Wikipedia

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

The resist responds to the total amount of energy absorbed. Thus, we need to define the Dose, with units of energy density (mJ/cm2), as the Intensity (or power density) times the exposure time. •We can also define D 100 = the minimum dose for which the photoresist will completely dissolve when developed. •We define D
