What Exactly Is A Micro-Lens? Find More Details Here!
As the name suggests, a micro lens, also called micro-lens or microlens, is a small lens with diameter less than one millimetre. Microlens is designed in a way that the substrate is actually thicker than that of the actual lens, which is why these lenses are designed by companies that specialize in prototyping and are capable of understanding optical components. There are advanced micro lenses too, which rely on aspherical surfaces. Today, the demand for high quality custom micro lens is huge in many industries, and these lenses are used extensively in diverse consumer products. You will also find what is called GRIN lenses, or gradient index lenses, which basically have two flat & parallel surfaces. Fresnel lenses also belong to this category, which use curved but concentric surfaces.
Here are some of the other aspects worth knowing about micro-lens.
More on micro-lens
You need to know of what’s called of micro-lens arrays, which basically contain many lenses, which are designed in an array on something called the substrate. The arrangement of the lenses depends on several factors and function desired, but there is usually some gap between the lenses in case the individual lenses have noncircular apertures.
What are the various applications?
The use of microlens arrays is common for CCDs. Micro lenses are used for collecting and focusing light that on the sensitive areas of the CCD array, which is the precise reason why microlens arrays are used for projectors and LCDs. It also has considerable role to play in photovoltaics, while researchers also use these lenses for different projects. In general, microlens arrays are used for making many common products, including cameras used in smartphones and photocopiers. For illumination needs of optical microscopes, micro lenses are often used, while the use of arrays is also common for displays and even for 3D imaging. Some of the 3D TVs that don’t require any extra glasses rely on microlens. For cameras, the use of micro-lens arrays is extensive.
If you want to order micro-lens arrays for a specific project, check online for companies that deal in optical components and offer a comprehensive budget for your requirements. The company should specialize in both prototyping and manufacturing and should have the necessary capabilities to do the project as per specific needs. Many researchers also rely on micro-lens arrays for finding more details on how these micro lenses can be used for achieving different goals in optics.
