"lasers we use are well under the eye safety limit and have been certified as Class 1 eye-safe lasers by third party labs."

I'm a bit surprised by that since IIRC 850 nm can go through the water in your eye to reach your retina but won't trigger a blink reflex. So it has to be pretty low power to get that rating.

905 nm can also go through the water in your eye (the eye safety limit for 905 nm is maybe 2 times higher than for 850 nm), but Velodyne and many other lidar companies have been using 905 nm for years with no problems. The 2x higher sensitivity of silicon CMOS detectors to 850 nm in comparison to 905 nm makes up for the lower power.
