Botvac D5 - laser diode failed ?

Postby bobbo » May 22nd, 2019, 11:48 am

Hi, one of my Neato D5 started coming up with error 4000. After spending most of the day disassembling it and its brother, it appears that the laser diode had failed (when I swap it over it works) Anyone know of its specs (wavelength and power) or where I can purchase the diode alone?

Did you swapped the whole lidar assembly or just the diode itself?

Hi, I just swapped the diode and it worked fine. Got any info on the diode ?

Well, some of the ebay listing specifically state that it is not for the D5 and D3. The others look like the same item, without the warning. Hence why I was after some specs to be confident of getting the right part.

Aliexpress was going to be my next stoop, but I need some specs!

ok, so I found the specs:
Laser Parameters.• Wavelength 785 nm• Pulse Rep Frequency 1.8 kHz• Pulse Duration 200 usec• Peak Power 2.1 mW• Beam Diameter 2.3 mm• Beam Divergence -1.5 mrad

The beam divergence is a lot different from the older Neato models, hence why the older diodes aren't compatible. No luck so far in finding these diodes though. Any help appreciated.
