In the simplest terms, the microlenses are very small lenses (generally less than a millimetre) used to offer exceptional optical quality. These lenses were primarily used in microscopes in the 17th century but now they have a wide variety of applications in different fields. Currently, the fabrication of a micro lens has become way easier with laser catapulting, an innovative technology to produce small lenses with customized properties like focus and shaping.

If you’re wondering about the applications of such small lenses, you have just come to the right place, keep scrolling to know all about the widespread uses of microlenses in photography, Smartphones, 3D imaging and more.

Light-field cameras

Unlike the conventional camera that is used to record the light intensity in a particular scene, the light-field cameras are designed to also analyse the direction that the light rays are travelling in any given space. These cameras use microlens arrays, which are placed before an image sensor to record the intensity of light, its colour and direction. There are two main types of light-field cameras based on the position of the microlens array. While the conventional (or standard) plenoptic cameras are used for close-range applications, the focused plenoptic camera is used for getting images with higher spatial resolution.

Video projectors

The video projector, also known as the digital projector, works to capture video signals from a source and project the image on a screen with the help of a microlens system. The microlens array, used in the video projectors, helps focus light on the LCD screen to generate the image. These projectors find a wide variety of applications in the corporate offices (during conferences), in the educational institutions (during seminars and other educational programs), and of course in the movie theatres.

Electricity generation 

Microlens arrays are extensively used in the photovoltaic industry to concentrate the high-efficiency photovoltaics and generate electricity. As the light rays fall on the microlens, which is placed on the curved photovoltaic glass substrate, they get absorbed and scattered to the attached solar cell. The phenomenon increases the efficiency of solar power generators about 4 times even on a cloudy day.

The microlens arrays are also used in the 3D imaging industry, as it forms erect images, unlike the inverted ones formed by conventional cameras. They are also used in the Smartphone cameras to produce depth and clarity, as well as in some photocopiers.

If you’re looking for customized microlens arrays for any of the aforementioned or other applications, you can get in touch with a reliable company that produces a wide range of such optical components and spoils you with choices. Better do some researches on the quality of the products, before you decide to buy them.
