Abstract
An infrared energy detection system having an infrared detector and a cooling system including a fluid coolant for cooling the infrared detector. An optical system is provided for directing infrared energy from a target to the detector though an optical system. The optical system includes a housing having a plurality of stops, each one of the stops corresponding to one of a plurality of fields of view of the optical system. A first lens is fixed within the housing. A second lens is slidably mounted within the housing and engageable by the plurality of stops. The second lens has a first resting position when engaging a first one of the stops. A fluid actuator system is provided for sliding the second lens away from the first stop to a second resting position when engaging the second stop.
