laser material processing machinery from Focuslight Technologies

The UV Line for Solid State Laser Lift-Off (LLO) from Focuslight Technologies has been successfully used for years in the lift-off field of OLEDs in the production of flexible mobile phone displays.

The development team at Focuslight has now enhanced the optical design far enough that the Gaussian profiles can be turned into a line with a length of up to 1000 mm and a width of 30 µm. The new features include significantly steeper edges and a wider intensity maximum. This allows an increased productivity by more than 30%. In addition, the sensitive OLEDs are subjected to lower thermal loads (lower ash value), yields are higher, and the OLED displays produced have a longer lifespan.

For the laser lift-off process of displays, we offer UV-Lines with different line lengths from 100 mm to 1000 mm. In addition to complete systems with long lines for integration into production, Focuslight also offers cost-effective systems with shorter lines, which can be used in advance in the process development.

Focuslight offers micro-optics manufactured on wafers. The wafer-based production technology produces polished wafers up to 300 × 300 mm², making it possible to produce tens of thousands of lenses from high-grade glass and crystal in a single process step, with a consistently high level of quality. Combined with a significantly expanded production capacity, Focuslight’s highly productive and cost-efficient operations mean that the company can sustainably meet the growing global demand for optics in innovative photonics- and laser-based applications and technologies well into the future. The surface shape of every single lens of a micro-lens array can be individually designed to yield the best intensity distribution, while our high-precision manufacturing process on a wafer basis provides a high rate of repeatability and reproducibility. Combined with the choice of various glasses and an ISO9001 qualified coating, we can offer a wide spectrum of long-life micro-optics solutions.
