A NEW AND ECONOMICAL PROCESS OF MANUFACTURING GLASS PRISMS AND A NOVEL WINDOW GLASS PLATE AS BY-PRODUCT-

摘要

This economical process of manufacturing glass prisms and the by-product namely Rainbow Window Glass Plate were developed through research into cost-reduction of the surface finishing methods ,to obtain low-cost refracting surfaces of optical standards.An economically finished and thin glass plate is glued to the ground surface of the glass prism (ground to the required angle of prism) using a transparent adhesive, without the possibility of leaving any trace of opaque layer in the joint. Such assemblies, which are of optical standards,are cured properly, cut into the required lengths,and de-burred for use as prisms.This process will usher in an era of availability of economical prisms, which in turn,will open up amazing possibilities to put this wonderM phenomenon (of sunlight getting split into attractive and brilliant rainbow colours)to everyday use of common man.This by-product is one example.
