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??
