An excellent element for improvement of vision is the Glass Ball lenses. They are possibly the best for the signal coupling among fibers, emitters, as well as detectors. Fabricated from single substrate of glass, they can focus or collimate lights as the case might be. In the process they hinge upon the geometry of the input sources. Usually the task accomplished by the ball lenses including low TG ball lens is one of the coupling elements for any type of optical fibers.
Application of Anti-Reflection Coating
Usually the use of anti-reflection coating is meant to minimize reflections on the lenses. In result their transmission powers are increased considerably. In general the ball lenses have diameters that range from 0.25-8.0 mm and each of these balls is inspected in detail to spot out defects, if any in them. This is a mandatory process followed before their delivery to the customers. Lenses also include half ball lens among others.
Production of Polished Lenses
To produce polished lenses they are worked out on mechanical surface and each of the lenses carry some optical qualities. When the final components are manufactured they are packaged into some waffle like plastic trays and this ensures both quality as well as the safety of the materials. Sometimes ruby ball is also used to make the lenses colorful.
Glass Ball Classic Features
Features of glass ball include uniformity as they are precisely ground as well as very low scratch digs. With roughness that is on lower side they are manufactured using a host of materials for quality and precision. Materials that are used for manufacturing them include optical as well as various colored glass products. They include both technical and the special type of glasses and the low TG ball lens is manufactured using low tg glass materials. Sometimes index glass materials are used that are refractive in nature.
General Application of the Ball Lens
Ball lenses are used for various purposes. Some of the common applications are in the field of endoscopy, systems that are used for optical measurements and projection, precision molding, as well as the barcode scanning processes. Yet another wide use of these glasses and lenses are in the switches.
Half Ball Lenses
A Half Ball Lens is basically fiber that couples half-sphere lenses and they can be easily interchanged for creating compact designs. These half balls are called hemispheres and are considered to be specially cut ball lenses in the optical use. Diameter of these lenses comes in the range of 1.0 mm through 10.0 mm with varying thicknesses and requirements of the customers. Variances of dimension range in the quantum of 0.002 mm only. Surface qualities and sphericity are the two factors that are taken into consideration during the use of the lenses.
Perhaps the most important use of these balls including ruby ball is in the field of LED lights where high precision dimension control, surface quality, and scratch proof surfaces are created and these products have small surface roughness and at the same time great heat resistance and high refraction index.
