With respect to an adaptable optical system, the task is to provide an active system prone to minimal failures, which can be used to vary different thermally dependent imaging properties in order to compensate for temperature fluctuations within a broad temperature range. The adaptable optical system comprises, in at least one embodiment, at least one optical component made of a material having a thermally dependent refractive index and/or coefficient of expansion, and means for introducing a temperature gradient into the optical system as a temperature difference between optical components, or into at least one optical component, wherein the refractive power or correction state of the optical system can be varied by way of the temperature gradient to be introduced in that a redistribution of the thermal energy takes place directly in an optical component and/or an exchange of the thermal energy takes place between the optical components. An energetically particularly advantageous variant is to combine cooling and heating elements. |
