Abstract
A collection optics having variable magnification, and which enable changing magnification without stopping the spray cooling. The variable magnification is provided by a turret that carries several objectives of different magnifications. A frame is provided above the turret, wherein the spray cooling is provided. By rotating the turret and changing its elevation, different objectives of the turret can be “docked” to a docking port within the frame.
