SWITCHABLE MIRROR LENS SYSTEM FOR REDIRECTING LASER ENERGY DURING PERIODS OF NON-PRINTING

A laser imaging system and method for printing includes a digital micromirror device and a switchable mirror element that acts as a clear lens element during the printing by the laser imaging system. A laser diode array provides a laser to the switchable mirror element in a laser path, wherein the s...

More Information
Summary:A laser imaging system and method for printing includes a digital micromirror device and a switchable mirror element that acts as a clear lens element during the printing by the laser imaging system. A laser diode array provides a laser to the switchable mirror element in a laser path, wherein the switchable mirror element is located in the laser path between the laser diode array and the digital micromirror device to divert energy out of the system and away from the digital micromirror device during periods of non-laser imaging without reducing or powering down the laser system.
