| Abstract: | Zinc sulphide remains transparent for infra-red rays, especially of 8- 12 micron wavelength. This material has a unique property of remaining unaffected by atmospheric humidity and the heat generated by means of friction caused by the present dust particles. Even under such adverse circumstances its optical property does not get affected. In addition to this it is a very useful material due to its sufficient mechanical strength related properties. It is used in CO2 laser in optical components, laser guide system of missiles, doors of fighter planes, infra-red imaging instruments and laser communication systems. Chemical Vapour Deposition -CVD is an improved technique of manufacturing Zinc sulphide on large scale in various geometrical structures Using CVD technique we have developed various shapes at laboratory level. In this process two reagents zinc and hydrogen sulphide are clubbed together at gaseous state to form zinc sup hide. In this paper the manufacturing technique pertaining to infra-red laser transparent zinc sulphide has been defined in detail. |
