Classification: CPC G | IPC G

Claim 15:
16. A remote imaging module configured to rotate an image plane of light within an optical system, the module comprising:
a first objective having a first optical axis positioned on the remote imaging module, the first objective being an air objective; and
a second objective positioned adjacent to the first objective on the remote imaging module, the second objective having a second optical axis that forms an angle with the first optical axis, the second objective being a liquid-immersion objective; and
a separation device positioned between the first objective and the second objective, the separation device including a first side having a reservoir that is configured to contain liquid in which the second objective is immersed during operation of the remote imaging module and a second side having a window to which the first objective is directly adjacent that enables light to travel from the first objective, through the liquid, and to the second objective;
wherein the first objective and the second objective are mismatched with each other in that they are configured to be surrounded by or immersed in different media having different indices of refraction.
