9. Q: If I change the rotational speed of the M8 sensor within the 5-20 Hz valid range,
what happens to the laser fire timing? Does rotational speed affect heat production?
A: Changing the frame rate does not affect laser fire timing, nor does it have a
significant effect on heat production. The angular resolution will change as a result of
the changed rotational speed under constant firing timing. The 10 Hz frame rate
(recommended for most applications) corresponds to 0.06 degree angular resolution.
10. Q: Is the M8 sensor's plastic lens cap field serviceable?
A: Do not open the sensor! Per terms of sale, purchaser agrees to not disassemble,
reverse assemble, or modify the sensor, nor allow a third party to do so. A support
representative may update the cap in the field if absolutely necessary.
11. Q: We want to put the M8 sensor behind a plastic enclosure to protect it from
scratches and damage, as well as make it more difficult to tamper with or remove.
What materials do you recommend that interfere minimally with the LiDAR?
A: Any protective material that has good transparency in the 905 nm wavelength
should work well. There are two options in particular:
• For use in an R&D environment, you can use the Gray plastic sheet available at:

• For a production deployment, you can use the Lexan SLX2432 material to mold a
piece that fits into your system without blocking the optical opening of the sensor.
We recommend a thickness of 1.5 mm, but it can be thicker or thinner.
NOTE: Adding material can affect range, depending on its
transparency and thickness. Curving the material's surface can
impact range, sometimes significantly, depending on the
radius of the curvature.
12. Q: What should we do with M8 sensors that we no longer need or are at end-of-life?
A: Please contact your support representative to discuss disposal or return options
suitable for the particular factors in your situation.
