light diffraction grating
Diffraction gratings Diffract, Or split, light Periodically, meaning the light splits into several beams with a given angular separation. In this experiment, the first Period, n=1, will be the brightest spot on the index card (besides the straight path of the laser, of course) after the grating splits the rays from the laser pointer. Using the

Interference–Diffraction Parameter Determination. In a two finite slit diffraction pattern, characterize the relationship between slit width and separation based on the number of bring fringes in the central diffraction maximum. Physics II: Electricity and Magnetism, Spring 2007
A diffraction grating consists of a series of parallel slits, notches, lines, or steps (some kind of quasi-1D structure). When a plane wave is incident on this structure, each divot will act like a point source, emitting a spherical wavefront (or more accurately, a cylindrical one).
I was hoping this film could be used to make my own firework glasses. :(it defracts the line only 1 way though, so I had to cut and rotate the film making 4 pieces per eye.
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 grating normal, and θ’ is the angle of diffraction measured from the grating normal. The overall efficiency of the gratings depends on several application-specific parameters such as wavelength, polarization, and angle of incidence of the incoming light. The efficiency is also affected by the grating design parameters such as blaze
Holographic diffraction gratings typically have a sinusoidal surface profile generated optically by recording an interference pattern onto a photoresist-coated substrate. The photoresist is then coated with a vacuum deposited metal layer to produce a master grating, which may be used as a mold to produce replicated gratings.

A visual grating structure editor; Automatic generation of common diffraction grating profiles including square wave holographic, blazed, sinusoidal, trapezoidal, triangular, 3-point polyline, and many others
A holographic diffraction grating is produced using a photolithographic technique. A diffraction grating can be a reflection grating or a transmission grating. The most common type of diffraction grating are plane gratings and concave gratings although they can also be other profiles such as convex or toroidal depending on the application
Diffraction Grating Slide-Linear 500 Line/mm Our Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (.). Diffraction Gratings are used for the direct viewing and analysis of spectra from different gas tubes and other light sources.
Grating elements can have luminances other than that of sharp-edged bars. If the graph of a grating is sinusoidal (see top panel in the illustration), the grating looks like a set of blurry light and dark bars and it is called a sine-wave grating. Sine-wave gratings are used extensively in optics to determine the transfer functions of lenses. A
Spectra of Lights: An Interactive Demonstration with Diffraction Gratings Page 1 Grades: 4th th– 12 grade Purpose: Students will explore the properties of different types of light bulbs using diffraction grating glasses to reveal the lights unique spectra or ^fingerprint _. The goal of the activity is for students to learn about types of
Diffraction Glasses are created by allowing light to strike a grating (in our eyewear this is the lens) which is marked with thousands of parallel lines, the light waves are caused to spread in such a way that they produce a spectrum, or rainbow, as pictured in the video above!
Diffraction of light takes place if the size of obstacle is comparable to the wavelength of light. Light waves are very small in wavelength, . from 4 x 10-7 m to 7 x 10-7 m. If the size of opening or obstacle is near to this limit, only then we can observe the phenomenon of diffraction.
The Diffraction Grating. After light passes through the slit, a set of lenses or mirrors collimates the light (makes all light rays parallel to the optical axis) and delivers the light to the diffraction grating. A diffraction grating consists of a material containing a periodic variation in one of its optical properties.
