I'm looking to buy new or used 200mm spheres for laser scanning, terrestrial LiDAR. Where can I find accurate spheres for a reasonable price, new or used?
I am located in California, USA

Ping pong balls work and are close to your size request.
Painted ball bearings may be purchased by diameter, but the polished surface needs to be made matte.
Paul - I've recently invented a new 205mm laser scanning target.. ther are semi hemispherical (1/2 globe) aluminum cake pans (yes I said cake pans) which I paint flat white and coat with highway reflective crushed glass beads.. been testing them for around a year
depending on your scan density your software can automatically detect the hemispheres as full globes.. diy cost is around $25 each and the nicest thing is that they stack ..also I can put 6 targets in the space that one 10" sphere takes

How accurate do you need to be??

Hello Paul,
I can have you some leica scanners. leica is the best in the market for now.
