Why 515nm Direct Green Laser?
Why Green Laser become popular? Surely because of the visibility!
Green Laser has 8 times luminosity efficiency higher than Red Laser!
From the spectrum chart shows human visible light wavelength is located in between 400~700m which covered Blue, Green, and Red. Visibility also refer to luminosity function or luminous efficiency function describes the spectral sensitivity of human visual perception of brightness. Look at the luminosity chart provides in above, it may describe as Green Laser provides upto 8 times brighter than Red Laser based on same output power level. The brighter effect from Green Laser is not depends on power level but just because of higher human eye's sensitivity.
Coming with aged society and recent illumination technology dramatically progressed, a brighter indication, says Laser, has drew the high attention as an essential and critical issue. In the past, when Green Laser still built based on DPSS structure which is unstable indeed.
(For more detail about DPSS Green Laser, reader can refer to another article listed below)
Customers has been limited to use Red Laser in order to pursue a stable and wider temperature usage light source instead of DPSS Green Laser. However, to achieve a brighter effect by Read Laser, it has been asked to raise the output power but comes with higher power consumption inevitably.
Now, with Osram released semiconductor Green Laser Diode, a safer, stable and wider temperature ( -10℃~50℃ ) Green Laser solution has changed the perspective.
Raytac's employs Osram's LD has successfully developed the Digital Pulsed Ultra Low Power Direct Green Laser module. The superior module's performance provides customers a power saving, reliable stability light source good for commercial and industrial implements.
Therefore, to consider using Red Laser or 532nm DPSS laser to built up the products now has become out of the question!
