904 or 940 nm

[frillweeman]

In the defcon slides, you put both 904 and 940 nm for the wavelength of the light. One lidar vendor's specs say 904, and Wikipedia says 905. Amazon link says 940, but won't that get rejected by the filter on the lidar gun (899-909 nm)?

Thanks for pointing this out. I already bought some of the 940.

[YipYup]

Correct. LIDAR operates at 904/905nm. 940nm is not the correct wavelength. Check RDForum for more information.

So what your saying here is that what was built, presented and posted here will not work?
