Most microscopes can be retro-fitted with a motorised focus option. The standard motorised focus control provides step sizes as small as 0.002µm and provides excellent resolution for precise focus and repeatable positioning in the Z-axis. For large movements or when speed is required, the ProScan ®III focus motor can be driven at speeds of up to 20 revs/s. The focus motor is designed with a rotating cable system to prevent cable twist.
