Abstract
The invention contemplates a modular system of interchangeable and multiply-combinable objective-lens components for selective use with an operation microscope to enable improved viewing of small operational areas, particularly in areas which are in deep channels or recesses. The construction permits optional use of the instrument in the context of stereoscopic or split-beam binocular viewing, or as an endoscope. Viewing is enhanced by efficient light transmission of both (a) the light used for object illumination and (b) the optical transmission of the image to be viewed.
Claims13
An operation-microscope kit, comprising a binocular viewing module having a viewing end and an objective-attachment end, said objective-attachment end being adapted for detachable connection to a conventional objective lens of relatively large diameter for operation upon object areas that are relatively exposed and uncluttered, an adapter module adapted for detachable connection to the objective-attachment end of said viewing module, said adapter module having a central region adapted for detachable connection to an objective-lens mount of reduced diameter substantially less than said large diameter and said adapter module having prism means for folding the binocular-viewing axes to within the lesser-diameter capacity of said central region, and one or more objective-lens modules of substantially said reduced diameter and adapted for detachable connection to each other and to said objective-lens mount in end-to-end relation.
