ESAW  Holographic Kit (LO-5022)

Holographic kit is a professional set up for shoong holograms in academic and research instuons. The equipment includes vibraon isolated table, opto - mechanical modules, opcal components, sample silver halide plates, processing chemicals, etc. All components and modules used in the kit are of industrial quality and reliablity. By changing the laser source and recording plates, the equipment can be used for commercial hologram shoong as well.

(I) Creaon of Transmission Grang
The experiment involves the creaon of transmission grang Using holography on a silver halide plate. The grang pitch is governed by the angle between the two incident beams that hot on the plate. We provide all the opcs, opto - mechanics, laser, holographic plates, developing chemicals, etc. To perform the experiment. Our instrucon manual contains experimental setups, principles, procedures, step-by-step instrucons and required photographs for recording holograms.

(ii) Recording and Reconstrucon of Transmission Holograms

The setup for the creaon of reflecon hologram is same as transmission hologram except the reference beam is lit from behind the plate. Controlling the beam rao is very important in creang reflecon holograms. We use variable beam splier for the purpose. In the case of reflecon hologram, a truly three-dimensional image can be seen near its surface. The hologram is illuminated by a “spot” of white incandescent light, head at a specific angle and distance located on the viewer’s side of the hologram. 

(iii) Recording and Reconstrucon of Reflecon Holograms
To create a transmission hologram, laser beam is split into two. The beam reflected from the object is called object beam and the other one, a plane wave without any informaon, is called the reference beam. The exposure me varies from seconds to minutes depending on the object. Absolutely stable condions are required during the exposure of the film. Variable beam spliers are provided to finely adjust the beam rao. To reconstruct the image, the plate is developed in the developer soluon and is placed in its original posion compared to the reference beam during its recording.
