07 Nov 2006 Resolve Optics Ltd has been selected by a leading micro-machining systems manufacturer to be the supplier of a unique F-theta Laser scan lens for a 25W 532nm Q-switched Nd:YAG laser. Resolve Optics Ltd, a leading designer and supplier of specialist lenses for demanding applications, was selected by a leading micro-machining systems manufacturer to be the supplier of a unique F-theta Laser scan lens for a 25W 532nm Q-switched Nd:YAG laser.
Looking to achieve ultra-fine resolution laser cutting and etching, the micro-machining systems manufacturer required a F-theta scan lens that combined high performance, durability and compactness. 'Off-the-shelf' scan lenses for high-powered lasers typically failed to meet the demanding high resolution (small focused spot size), tight tolerance on spot size variation or lens durability specifications.
Using a novel telecentric design, the Resolve Optics 100mm focal length laser scan lens achieved excellent F-theta performance, with resolution (20 micron focused spot size) very close to the diffraction limit over a flat image plane. The variation of spot size from the average spot size over the full scanned field was minimal. A proprietary coating on the laser scan lens provided both high on-axis and off-axis transmission as well as the desired durability with a damage threshold 1000x higher than the laser power being used.
Applications for F-Theta scan lenses include high-energy density laser marking devices, graphic arts printers, image scanners and various information processing equipment used in the laser scanning industry.
Resolve Optics Ltd. is a highly knowledgeable, dynamic company focused upon innovative design, and manufacture of production quantities of lenses and optical products on time to strict quality and target price guidelines.
