ABSTRACT:
A microscope objective lens positioning assembly comprises a lens mounting member to which a microscope objective lens defining an optical axis is mounted; a support member; and a pair of leaf springs. Each leaf spring has first and second ends, the first ends of the leaf springs being secured to upper and lower aligned locations respectively on the support member, and the second ends of the leaf springs being secured to corresponding upper and lower locations respectively on the lens mounting member whereby the two leaf springs, the optical axis of the objective lens, and a line between the upper and lower aligned locations on the support member define a parallelogram, the leaf springs flexing in use in response to movement of the lens mounting member.
