The wholesale electronics distributor Osram has changed the mobile phones into beamers. The need for projector applications to green lasers, to have not only outstanding beam aspect. Also a high visual work in order to give sharp and bright images. Even a projector also need red and blue lasers, green is the crucial color in RGB solutions. And also the color that poses the greatest challenges in production. The brand PLT3 520D continues Osram’s success story with green lasers. With the 140mW it achieves an original high pulse tor direct green laser diodes. In like manner, the expertise of the laser been increased to a common value of 8%. It is good for those improvements, it is now possible to turn a mobile phone into a small cinema projector.
The laser projector
The little array of the tools can increase many times over. Until now, RGB laser projections for mobile phones, based on a red, green, and blue laser, sometimes had brightness problems. It is because sometimes not enough brightness of the green laser. The reason is that green light has special importance in RGB applications. Because our eye is most sensitive in the green spectral range. The shining the green laser shines on a surface, the shiny and stronger the projected image appears to the viewer. The PLT3 520D now offering 140 mW at 300 mA in pulse mode with 50% duty cycle. The company Osram has achieved exceptional performance for a green single-mode laser.
As of now, the limit for these components was 80mW. An advance benefit of the diode is its compact and space-saving TO38 metal housing with a diameter of only 3.8mm. With a wavelength of 520 nm, the laser diode has specially developed for laser projector applications that use a MEMS scanner as the image encoder.
It is good for OSARM’s long tradition and ability in the laser sector. The company has succeeded in driving forward development in this key technology, according to the marketing manager of Osram. According to the quality that the company promised to their consumers. Lastly, the consumers can be confident that this technology will open up additional functions on a mobile phone in the medium term.
