Laser Optics for a Laser Line up to 250mm Length using Pulsed Solid State UV Lasers
The VOLCANO® 250UV Laser Optics is built into a solid granite structure. Two laser beams can be combined to obtain high energy density. The beams are processed by independent telescopes and combined by a specially designed homogenizer. The combined laser beams are homogenized into a 250mm long line beam with a typical width of 20 - 30µm. The FALCON 250UV projection lens assures a uniform line width and the large depth of focus which trouble-free production requires.
Scope of Application
Laser-Lift-Off processes are in use in the electronics industry for the production of flexible OLED displays for TV products, smartphones, smartwatches and tablet computers. The OLED display is manufactured on a flexible polymer foil on a glass substrate. The final polymer foil with the OLED display is lifted off the glass using the UV laser line.
