Optotune

Optotune offers four optical devices that exhibit unique tunable properties:

Manually tunable lens	Fast electrically tunable lens	Tunable phase shifter	Laser speckle reducer
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
