half ball lens

1.Basic structure and working principle of half ball lens

A half ball lens is one that is made from a portion of a sphere that has an equilateral cross-section. As compared to other lenses, they have a particular convex lens appearance and can be used in optical systems to aid in lighting concentration, imaging and magnification.

The basic design of hemispherical lens comprises two components which are the lens itself along with the lens’ holder. It is usually composed of either plastic or metal material that can hold the lens to optics. The lens itself could be made from plastic or glass and the exterior of the lens may be covered with various lenses to meet a variety of demands of the optical.

The underlying principle of lenses with hemispherical shapes is founded in the convex effect that occurs in lenses i.e. diffusing or focusing light within the lens. When light enters an hemispherical lens is reflected by the front of the lens, then reflected through the rear side of the lens. It will then become an axis of focus following a specific level of diffusion.

2.Field of application of half ball lenses

Since hemispherical lenses possess an effect of convex lenses and unique shape They are used extensively in photography, optical instruments and in image processing.

When it comes to optical equipment, hemispherical lens are used to accomplish tasks like imaging as well as light concentration and control of laser beams. For example, hemispherical optics are used in lens sets or lenses in video cameras to reduce image distortion and enhancing the quality of the field. Hemispherical lenses also are crucial components in optical instruments, such as telescopes and microscopes.

Field of application of hemispherical lenses

When it comes to photography, hemispherical lens are used in photography to make specific filters, like wide-angle lenses and fisheye lenses to capture distinctive photos and create visual effects.

In the realm imaging processing, these lens can be used to make specially designed cameras or camcorders to support the newest applications, such as stereooscopic imaging, virtual reality, and Augmented Reality.
