Optotune offers four optical devices that exhibit unique tunable properties: | Fast electrically tunable lens |
| | | ML-20-35 | EL-10-30-Series | TPR-8-40 | LSR-Series | |  |  |  | | The focal length is manually tuned by rotating the outer ring attached to the lens | The focal length is rapidly tuned by applying a control voltage to the connectors of the lens | The optical phase is shifted by increasing the optical path length through the phase shifter | Speckle noise is strongly reduced by dynamically diffusing the laser beam |
