Laser question

  1. Mar 1, 2004 #1
    Hi,
    I am a ME working on a toy design. I know next to nothing about lasers diodes.

    Is there a laser diode of low enough power that it could be safely incorporated into a kids toy? (visible "dot" required. Or is all laser light potentially harmful to the retina?

    Thanks!

    Does it have to be a laser? Could you just use a LED as the light source?

    Hi Don,
    I think it would have to be a laser as I need to reflect a narrow beam off several surfaces.

    Are you using it as "machine vision"? e.g. using it to locate where the toy is?

    Hi Don,
    Without giving too much away...
    I am using it to create a series of reflected visible beams as it passes through a suspended medium.

    Thanks!

    Just curious. Does it have to be visible light or could it be infered?

    Regards

    It must be visible for the effect I am looking for.
