You can't miss with this Zeiss i-terminal. The i-terminal is designed to demonstrate lens options, take PD's and seg heights, Capture and print high quality pictures of patients for frame viewing. This unit can also be set up to send the measurements directly to your lab. It is a table top unit but can also be placed on a stand. We purchased the terminal and used it a handful of times. We would like to sell it to an office that would have better uses for it. It is a very good machine and all parts, printer, software and original paper work is included. Zeiss has agreed to instruct buyer how to operate the i-terminal upon purchase (its really pretty easy). Please contact me mikei190@aol.com if interested. I originally purchased the unit for about $7900.00. reasonable offers will be considered.
