If you are interested in optical sensors or own a company that deals in proprietary optical products and devices, you should definitely know about microlens arrays. For the uninitiated, microlens arrays are arrays of small sub- millimeter lenses, which have diverse applications in the world of optics. From use in cameras and imaging to sensors and more, microlens arrays are required for different needs. Expectedly, microlens arrays have to be customized for each project or production needs, and there are companies that can help with getting configurations as required. You can always check online for a wide range of standard and custom microlens, but before that, here is a look at the basics.
Decoding the applications
The use of microlens for CCD arrays is pretty well-known. Basically, micro-lens helps in improving the efficiency of light collection for CCD arrays. These lenses can collect and help in focusing the light on the sensitive areas of the CCD as required. These arrays are also used extensively for production of projectors. Imaging devices rely on microlens arrays for diverse applications, so everything we know – phones to copying machines – has these lenses. The use of these lenses is also extensive for designing optical microscopes, because illumination needs to be absolutely uniform, for which microlens arrays are required. For displays and 3D imaging, microlens arrays are useful, and configurations can be prototyped as required.
Every company that requires microlens arrays has specific needs. From regular spherical lenses to aspherical ones, varied kinds of lenses can be required, and there are manufacturers who can offer custom microlens. If you are in need for two dimensional microlens arrays, you can contact one of these companies, and they will get the prototyping done. There are also one-dimensional microlens, and as needed for a project, you can even design square and hexagonal ones. In case of microlens, both closely-packed and gap-based lenses can be ordered. It is best to check for companies that have been dealing in the field of microlens and optical sensors for the longest time, so that you can seek tailored solutions. Masters are usually offered in fused silica and nickel.
Check online to find more on microlens arrays and applications, and make sure that you order your products from a company that can be relied on. The quality and configurations are more important than anything else in the world of optical parts and components.
