Replication is the process of manufacturing optics by transferring the optical surface of a master (or mold) to one or more copies of the surface. The copies, which only approximate the final surface before replication, then take on the precise characteristics of the master surface.
The experimental setup is very simple and consists in pointing the beam laser emitted from the He-Ne source on the diffraction grating. The beam undergoes diffraction and produces on the screen behind the grating the diffraction pattern with the first and second order maxima.
In this paper we describe an experiment in which radiation emitted by an infrared remote control is passed through a diffraction grating. An image of the diffraction pattern is captured using a cell phone camera and then used to determine the wavelength of the

A typical diffraction grating consists of a substrate, usually of an “optical material”, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum.
“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.
A grating has 350 rulings/mm and is illuminated at normal incidence by white light. A spectrum is formed on a screen 30cm from the grating. If a 10mm square hole is cut in the screen, its inner edge being 50mm from the central maximum, what range of wavelengths passes through the hole?

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.
An arrangement consisting of a large number of equidistant parallel narrow slits of equal width separated by equal opaque portions is known as a diffraction grating. The plane transmission grating

Diffraction is the spreading out of waves as they pass through an aperture or around objects. It occurs significantly when the size of the aperture or obstacle is of similar linear dimensions to the wavelength of the incident wave.

In the case of Fresnel diffraction, the source (transmitter) and the detector (receiver) are at a finite distance from the diffrac-tion object. With increasing distances, the Fresnel diffraction patterns are increasingly similar to the Fraunhofer patterns. Fig. 1: Schematic representation of the diffraction of ultrasonic waves at a slit.

If you shine light, or other types of EM radiation, through a series of small slits the waves interfere causing constructive interference at certain points. We can then use this method to
Diffraction: Coherence in Optics presents a detailed account of the course on Fraunhofer diffraction phenomena, studied at the Faculty of Science in Paris. The publication first elaborates on Huygens' principle and diffraction phenomena for a monochromatic point source and diffraction by an aperture of simple form.
At the upcoming SPIE Photonics West trade show (7-12 February 2015; San Francisco, CA), scientists from the Fraunhofer Institute for Photonic Microsystems (IPMS; Dresden, Germany) will introduce a mobile MEMS scanning grating spectrometer in "sugar cube format" for spectral analysis in the mid-infrared range (3 to 12 µm).
