    The Wavelengths used are 0.905microns to 1.55microns, while Class A, they are still lasers.

    If you happen to be carrying the right sort of material on your skin for example, the wavelength could halve or quadruple. That would locally irradiate you at UV or microwave.

    People looking straight at the sensor could get cataracts or irritated corneas.

    Its unnecessary technology exposing everyone around it to new unknowns.

        I mean if they’re going to misuse words, might as well do it with confidence

      Let’s say it halved. That’s visible light, which at low wattage, is harmless.

      If it quadrupled, its still infrared. Also harmless at those wattages

      Remember here: youre dealing with something that is less harmful than visible light. So whatever fear you have must be much worse when it comes to things like daylight, indoor lighting, headlights, etc

      If near infrared (1000nm) can become uv with the wrong material, surely visible light from the sun can do the same and would become an even more dangerous wavelength? Or is this an effect that only happens to near-infrared? Ive not come across it before…

      Wouldn’t that sort of material also double the frequency of any other light source? Like a street lamp or the sun?
