HO-ED-H-02 Holographic Lab

Holographic Lab Holmarc's Holography Lab (Model: HO-ED-H-02) is developed for recording holograms in academic and research institutions. The equipment includes, vibration isolated table, opto-mechanical modules, optical components, sample silver halide plates, processing chemicals etc. All components and modules used in this kit are of industrial quality and reliability. By changing the laser source and recording plates, the equipment can be used for commercial hologram recording as well. In depth training in hologram making is given for all our customers free of cost at our holographic laboratory with either He-Cd or He-Ne lasers Holography is known as “lens less photography” in which an image is captured not as an image focused on a film, but as an interference pattern at the film. The recorded holographic image has both phases and amplitude information where as a photographic image has only amplitude information. A coherent He-Ne laser (632.8nm) is used as the light source. A variable beam splitter splits the laser beam into two. One of the beams illuminates the object and the scattered light from the object illuminate the holographic plate while the second beam directly illuminates the holographic plate. As the path length of both beams are equal, interference fringes will form at the holographic plate and will get recorded. The recorded plate is then chemically developed by washing in developing solution. The developed plate, under proper illumination, produce a three dimensional image of the object. Experiment:    Recording of Diffraction Gratings    Recording and reconstruction of Transmission    Recording and reconstruction of Reflection Transmission Holograms A transmission hologram is one where the object and reference beams are incident on the photosensitive plates / films from the same side. A recorded transmission hologram can only be reconstructed using the same light source which is used for recording. Reflection Holograms A reflection hologram is one where the object and reference beams are incident on the plates from opposite sides of the plate. The reconstructed object is then viewed by white light from the same side of the plate where the white light is incident. Holographic Transmission Gratings A holographic transmission grating is one where two reference beams are incident on the plates from the same side. The resulting straight line interference fringes will get recorded by the plate. When a white light passes through the transmission grating, it will split the Grating white light into its component spectrum.
