'diffraction grating'

Dot-Matrix Hologram Dot-matrix holograms are made from high-quality raw materials and consist of many tiny dots and pixels, each with its diffraction grating. Because of the number of effects, the dot matrix hologram has more security features than a 2d/3d hologram, making the holograms more secure. As a result, it is regarded as the best commercial security application. Kiran Holographics is the best manufacturer of dot-matrix holograms.

The Hologram Master Origination works on the principle of sending light beams which can be broken and sent using lenses at a number of angles to create an interference pattern which is recorded in the form of an image over a glass plate. This artifact, made with a nickel mould, plays an important role during the making of holograms. The creation of holographic pictures helps masters counter product counterfeiting. By amplifying light beams and applying lenses, we produce an individual combination of interference-type security features on the glass plate. These features, which are both 2D and 3D holograms, are highly instrumental in preventing counterfeiting attempts. The hologram creation offers a genuine set of security features, including images produced by laser optical recording, dot-matrix holograms created by innumerable grating dots at various angles, and true color holograms created by photographic techniques. In addition, nickel molds are a protective feature in the hologram creation process.

Named after the French physicist Augustin-Jean Fresnel, these holograms use a simplified diffraction pattern to create 3D images. They are more compact and thinner than traditional holograms, making them suitable for applications where space is limited, like automotive head-up displays and augmented reality glasses.

Kiranholographics will give the protection hologram and hologram security decals with thermochromic Ink' that react to changes in temperature by altering from coloured to colorless' using an increase in Temperature and out colorless to colored' if the temperature drops. we can give security hologram and hologram stickers beside other safety inks like ultraviolet radiation ink, fluorescent ink, and Optical factor ink, IR security inks, Sun-light sensitive security ink, etc..

E-beam hologram developed by technology of the formation of small relief originally developed for microelectronics.Electron Beam technology differ fundamentally from optical technologies because it uses electron beam, which can be very accurately focused with electromagnetic lenses. This e-beam technology can even succeed a resolution of 10 nm (0.01 micron). We can get e-beam holograms for government of Rajasthan with special feature like : high-resolution line patterns,Switch impact,Kinematic pictures,Concealed pictures,True color pictures,Micro-texts (25-150 micron),Nano-texts (~ five micron),CLR pictures (including dynamic and multilevel) to be controlled by special laser device,Images recorded by special shape pixels. Kiranholographics turn out special forensic cryptograms—hidden diffraction pictures which can be known solely specialized Optical laboratories.
