An Optical Lens is a transparent optical component used to converge or diverge light emitted from a peripheral object. The transmitted light rays then form a real or virtual image of the object.
Lenses are a good example of transmissive optical components, meaning that they pass or transmit light. Other transmissive components include filters, windows, flats, prisms, beamsplitters, and waveplates, while the opposite category - reflectives (which reflect light rather than transmit it) - include optical mirrors and retroreflectors.
Optical lenses have been used since at least c. 700 BCE for a variety of applications, including:
Magnification
Correction of optical aberrations
Use as a firestarter (burning-glasses)
Image focusing
Image projection
Hanzhong Hengpu designs and manufactures optical lenses for industrial, medical, high tech and electronic applications. Standard and custom lens assemblies for scanners, CCTV, CCD/CMOS, medical imaging, surveillance systems, machine vision and night vision systems. Universe Kogaku`s lens application engineers provide your optimal lens solution.
We`ll assist you with all of your design considerations-from lens assembly and overall design specifications to budgets and timetables. And we can reduce your project costs with our extensive selection of standard lens assemblies and elements, value-added services for component modification, and with custom designs that often eliminate the need for other components or modifications in your design.
