The Gardasoft TR-CL180 is a single-channel industrial Lens Controller which provides very accurate and repeatable control of tunable lenses. The TR-CL180 has been developed in close collaboration with Optotune. The TR-CL180 includes a precise, constant current drive for the liquid lens and is able to read data stored within the liquid lens. It is compatible with Optotune EL-10-30-Ci, EL-16-40-TC and EL-3-10 tunable lenses.
