Not only are consumers demanding high quality precision gadgets and equipments, but the manufacturers are stressing on producing such items. In the modern world, technology has changed for the better, in such a sense that it allows people to use products, which have higher precision and better output. Compared to the past, equipments are being manufactured with better efficiency, thereby reducing the overall cost of buying and maintaining products. Mostly in the field of fibre-optic instruments and electronic gadgets, there has been a complete overhauling of the ingredients used in their functions. This has been attributed primarily to the use of glass balllens in variety of instruments.

Particularly in instruments, where there is need to come up with rotatory or sliding movements, friction is a major hurdle for the efficiency and output. In recent years, this detrimental factor has been corrected using the glass ball and half ball. Various medical diagnostic tools, where fibre optic principles are used, have the use of such balls. Even probes, based on fibre optic instrumentation have been using these round spheres made of glass. Another amazing use of the half ball lens has been in LED instruments, starting from endoscopes to the modern day television sets. Many aviation instruments, laser devices, and multitude of other industries are utilising these kinds of balls for adding superiority to the instruments, thereby increasing the output and efficiency by a significant level.

• Another kind of ball which has been in industrial use for making products of precision is the ceramic ball. In food processing units, lens making, bar codes, watches, tachometers, and various other instruments, ceramic ball has secured an irreplaceable use. Equipments where there are parts, which need to move over each other or rotate along an axis, the balls made of glass and ceramic can be a great value addition.

• The huge popularity in the present day industrial scenario, of the glass ball or ceramic ball has been attributed to two important characteristics of these structures. Not only are they used for these properties, but the overall cost of obtaining these is quite economical. Moreover, they help in allowing the function of the instruments to be carried out for a long period, due to which there is reduction in the damages of the parts. This adds to the longevity of the instruments, thereby effectively reducing the expenditure on the instruments by any organisation which procures such instruments.

• Being perfectly round and smooth, the half ball or full ball lens can reduce the friction significantly. Also, they have been moulded in such a manner that it becomes difficult to be broken. Ceramic further has the properly to be broken very rarely. Lowering of friction in the instruments is a reason for the increasing popularity of these kinds of balls.

Furthermore, the heating capacity and refractive index of the half ball makes it highly suitable for being incorporated in probes, LED surfaces and various other optical instruments. This adds to the efficiency of the instruments, at costs which are probably lower than adding any other instruments. Nowadays, for these reasons, the usage of equipments with glass and ceramic ball has increased significantly. People are interested to buy such sophisticated instruments for their personal use. This adds to their comfort and convenience of use and their expenses are worth the money spent. Even industrial units are banking on these structures to add to their efficiency and hence their popularity.
