Abstract
Optical assembly comprising a variable focal length lens assembly comprising a variable focal length lens and an actuating unit, wherein an energy absorption rate of energy absorbed by the variable focal length lens assembly depends on the applied controlling signal. The optical assembly comprises a controlling unit configured to control focal length settings of the variable focal length lens by providing respective controlling signals and to apply a default controlling signal for providing a default focal length and default energy absorption rate. The controlling unit provides a thermal stabilisation functionality, the thermal stabilisation functionality is defined by applying a varying controlling signal related to a varying focal length and applying a compensation controlling signal related to a compensating focal length.
