Device for tempering a laser module in a printing plate exposure unit

摘要

A temperature of a laser module (4) having at least one laser diode for imaging a printing form in an exposer and a Peltier element (14) is controlled by cooling the laser module by leading heat from the laser module to the Peltier element through a heat conduit. The laser module is cooled and heated by leading the heat from and/or to the laser module through the heat conduit and/or Peltier element. An independent claim is also included for an apparatus for controlling a temperature of a laser module.
