Lidar FOV issue

Hi, I am wondering about the FOV of your mini lidar products. Spec says aroud 2-3 degrees. I am looking for a mini lidar device that sends out a much smaller dot and calculates distance to a point at a distance of about 2-4 meters (lika a normal laser rangefinder)? Is it an embedded lens inside the lidar device that can be manipulated to modify the focus, or is this regulated? E.g. for safety reasons ??

Thanks in advance
Best regards
