Micromirrors for High Definition Laser PrintingLemoptix silicon-based, magnetically actuated MEMS micromirror technologies are efficient and cost effective alternatives to conventional polygon mirror, LED array and external coil-magnet mirror assembly solutions, bringing leading-edge performance and space reduction to laser printers. Responding to industry requests to significantly reduce size, power consumption and increased performance of micromirror devices, Lemoptix has replaced traditional galvanometer and rotating mirrors by micromirrors with actuation based on magnetic and heat-dissipating principles instead of gearings. These laser scanning micromirrors can be used in numerous optical applications such as 3D measurement, barcode scanners, endoscopy/confocal microscopy, optical spectrometers & medical imaging, scanners, printers, head-up displays, projectors etc…. When incorporated into equipment like laser printers, they can potentially reduce the costs of manufacturing of these equipments while at the same time, improve their performance, increase the printed page throughput and shrink their footprint. Lemoptix optical scanning mirrors provide a number of advantages. The devices can achieve high optical scanning rates, low power consumption, low voltage operation, greater durability and immunity to dynamic deformation during operation and precise/stable control of the mirror positioning thanks to integrated sensing control. The scanner can operate at high scan frequencies, up to 70 kHz with a high-precision positioning, over a large angular range up to 100° optical angle, thus reducing image banding. This gives the device a scanning resolution far over thousands of pixels per scan line, making it possible for the development of ultra-high resolution laser printer equipment. They operate at a very low operating voltage and current, thereby allowing it to consume less power than conventional laser printer solutions.
