Ophthalmological Optical Device for Modifying a Treatment Laser Beam and an Ophthalmological Laser Treatment Device Comprising the Ophthalmological Optical Device

An ophthalmological laser treatment device comprising an ophthalmological optical device for modifying at least one parameter of a treatment laser beam used for treating an eye of a patient, the ophthalmological optical device comprising:

• a housing, which is configured to provide in an interior of the housing an atmospheric environment, which differs from an atmospheric environment outside the housing,
• an optical component, which is arranged in the interior of the housing, and which is configured to modify at least one parameter of the treatment laser beam when the treatment laser beam interacts with the optical component,
• a support assembly, which is arranged at least partially in the interior of the housing and which is configured to position the optical component in the interior of the housing,
• a temperature control assembly, which is configured to control the temperature of the optical component, and
• a temperature sensor, which is configured to provide a sensor signal, which is indicative of the temperature of the optical component.
