LED - OLED
The biggest advantage of this technology is the possibility to produce a large light emitting surface in a very thin housing (only few mm high). As with LEDs, OLEDs offer the possibility of controlling the intensity and the exposure time. OLED technology illuminates intrinsically and as such heat generation is a far lesser problem. This technology is still very young, however the technology is progressing rapidly with new products being announced delivering a longer lifetime (up to 50,000 operating hours), higher efficiency (up to 100 Lm/W) in a range of colours and illuminator sizes.
First products dedicated to the machine vision market are now available (principally backlights) and we expect to offer flexible and transparent OLED products in the near future.
