                A polarizing film allows the light oscillations to be shifted from 360 degrees to one direction and make it appear differently. Polarizer film is one of the core elements of LCD, helping in polarizing light and with the focusing lenses. A 3D polarizer film enables the establishment of a polarized 3D system using polarizing glasses to create a three-dimensional image by restricting the light rays.

In the laser path, the last to be hit before the workpiece is a focusing lens, its role is to focus the laser beam on a specific FL. Two types of focusing lenses are as follows:

  • Plano-convex lens
  • Meniscus lens

The focusing ability of lenses

                The focusing ability of a lens can be calculated by the lens' makers' rule for thin lenses, as the focusing ability of a lens depends upon its focal length which is affected by the index of refraction of the glass, the radii of curvature and the medium in which the lens resides. The focus of a lens defines its class. For such cases large-aperture lenses with a large open aperture not only provide superb imaging power but creates a shallow depth of the field, making the subject out from the background. This ability proves to be of great benefit in camera lenses and photographic films.

3D characteristic

 Anaglyph is the study of used in glasses or the 3D effect achieved by encoding each eye's image using filters of different colors. In 3D glasses, two different colors of glasses are used to give a 3D effect. 3D projections have been available in various forms for a very long time. 3D technology uses two overlapping images to increase the viewer's perception of depth. The anaglyph method is used for current 3D DVDs and Blu-ray discs. The one problem that rises is 3D effect tends to cause more eye strains than other technologies resulting in eye strain induced headaches.

Polarizing lenses

                Polarized lenses reduce light intensity and also reduce glare. Even proper eye care to avoid glare requires polarized sunglasses, which people usually wear after ophthalmic surgeries. Light polarizing systems are used in commercial cinemas and other high-end applications, providing high-quality 3D experience and amazing picture quality. The colors are more accurate and definite. There are two different polarizers-based systems, currently used for commercial 3D projections. Polarized glasses help viewers to see only the information intended to them. Polarizing lenses are used in iPhone, cameras, glasses and other devices for a picture-perfect image to avoid impurities, interference, etc.


                These lenses and polarizing films are of great importance in laboratory works, scientific researches, medical studies, and much more. The lenses for focusing do not require much equipment. Even the eyesight glasses we had focusing lens fixed. The lenses help converge the light and see the image clearly, enhance the quality of the image by polarizing them. Due to the help of lenses, we have done a lot of study on microorganisms and in other microscopic fields. These all have great work in the field physics, always had and will always have.
