为什么要对VCSEL检测 |
Why VCSEL need to be inspected? |
★VCSEL是由几千甚至上万个激光器组成,需保证所有激光器良好的一致性,才能保证VCSEL的亮度和均匀性。 |
VCSEL is composed of thousands or even tens of thousands of lasers. It is necessary to ensure the good consistency of all lasers to ensure its brightness and uniformity. |
★VCSEL对激光的坏点数有要求。 |
VCSEL only accept a few bad laser. |
★VCSEL对激光的光束和发光角度有要求。 |
VCSEL has requirements on laser beam and its Angle. |
★VCSEL的光功率需要检测。 |
The optical power of VCSEL needs to be checked. |
★VCSEL的量产良品率不高,需要视觉检测筛选。 |
VCSEL mass production yield is not high, which need AOI for checking and sorting. |
