    Default Microvision laser projector

    I notice that the much-touted Microvision laser projector is available at last:

    Does anybody know what technology/wavelength/power LASERs are inside?

    Wavelengths are 442, 532 and 642. No clue about powers.

    Although I'd be very keen to see that 442 in action.

    I would think they'd legally have to keep it under 5mW ...

    But it's based on MPE, and since it is not a beam when it exits the device, the same power would be less likely to do damage.

    This one is projecting a beam, it uses a MEMS scanner to do raster scanning

    Therefore could still fall under the same issues as a laser projector

    I don't think it could be done with only 5mW/color. There must be an exception for display technology that utilizes lasers.. the power is spread over a very large area, so it doesn't seem far fetched to me that they would be exempt from the 5mW restriction on that merit.

    The specs are saying it outputs 10 lumens. According to Chroma, for a balanced white, output powers should be something like 13mW 532nm, 22mW 642nm and 12mW 445nm. Another thing is they says it's a laser class 2 product...
