Sorry yes, not 455nm, 445nm
I believe they do use raster scanning, since I think the losses would be too high if you tried passing it thru something.
It might very well be, and by the looks of the video, the green is also diode based (or they simplified the dpss part out).
Perhaps it has some kind of scanfail? Given the raster scanning, its not likely to expose anyone to dangerous levels of light, unless you hold it right in front of your eye.Where is the laser warning sticker? If it outputs more than 5mW, where is the key interlock, safety dongle, aperture shutter, and LED indicator?
If it were modulated with a DLP chip, it would cease to be a beam, and therefore pose no danger unless you intentionally focused the output with additional optics into your eye. If it isn't DLP based, they are unlikely to show warning stickers on a catalog picture of the product. Bad marketing.Where is the laser warning sticker? If it outputs more than 5mW, where is the key interlock, safety dongle, aperture shutter, and LED indicator? And is there a 2 second delay? Is it CDRH and FDA certified?
The output stated is 20 lumen. This equates to about 80 mW of light if its ideal white (when combined), perhaps a bit less if green is relatively too powerful.I said this before this unit does use directly injected blue and red diodes, the green is dpss.
I think the output power is allot more than 5mW, but as Benm said, the light is spread out over a lager area and thus is eye-safe.
I guess since it's moving, you'd need more power to burn. I guess the 100mW was too powerful either way. But if it was moving ridiculously fast (faster than scanner speed fast), it would not have burned the CCD. It's all about exposure doses.What I dont understand is how scanning speed makes thing safer for the eye.
I burned a good size notch in my old cam's CCD while running 100mW 405nm in a scanner.
It was in close proximity to the laser, approx 10ft, but I didnt expect it. The scanner was projecting a time tunnel type cone at the time, and I had accidentally passed the camera through its solid lined path.
Come to think of it, it would have been funny if the news cam in the video had a nice patch of holes in the CCD after filming the aperture of the pico projector :eg:
