Angular resolution and nominal range of Lidar-Lite

In the technical specifications provided for the Lidar-Lite (laser emitter version), the angular resolution is listed as 4 mrad with a nominal range of 60m (based on 90% [reflective?] target).

Robotshop lists the Lidar-Lite (laser emitter version) having a 0.5 degree angular resolution (roughly double that listed in the official documents; 4 mrad = 0.23 degrees) and having a 40m distance, which is about 20m less than the best case scenario listed in the official documents.

Can someone confirm that the model sold by RobotShop matches the actual technical specs as published by PulsedLight3d.com? If it doesn’t, can someone confirm that the angular resolution and nominal distance sold by RS is correct?

Cheers

We do apologize for any confusion. At this time the manufacturer only offers the one model at 40m.
We have contacted the manufacturer regarding the angular resolution and will get back to you shortly.

Hi there,

Thank you so much for your question!

Our data sheets and manual were causing some confusion and in the course of product development we tweaked a couple things. As of right now we are only selling the Laser Module with 0-40m range and 8 mrad angular resolution.

I’m currently updating all our documentation to reflect this.

Great! Thanks Austin.

I calculate a 8 cm circular footprint at 10 m. Is that about right? It’s not great, but it certainly seems to be excellent for the price point. Looks like Lidar-lite will be on the top of my shopping list.

I know you guys are probably busy with filling orders, etc., but is there any sense of when we can expect angular divergence to improve?

Thanks again to you and the 'Shop for the quick reply.

8cm at 10m sounds right.

The main reason for the beam spread is for eye-saftey certification. Our sensor has a diffuser in it to spread the beam enough that someone wouldn’t go blind if they accidentally stare at it (b/c its infrared, you wouldn’t notice until you had done damage).

We’re exploring ways to eliminate the diffuser from the product in the future, but right now that safety certification is what’s really standing in the way.

Great questions! Thanks so much!
