Objective Changing Appliances.

We supply the following appliances for rapidly substituting one objective for another:

Revolving* Nosepieces for two, three or four objectives, and Clutch Objective Changers with loose adapters for the objectives.

Double Nosepiece No. 131.

Triple Nosepiece with Guard Disc. No. 132.

Revolving Nosepieces, apart from the rapidity with which they serve to effect the transition from one objective to another, have the useful property that they can be so adjusted that, having focussed one of the objectives, one need not focus the others separately as they are brought into operation, excepting that a small turn of the micrometer screw may be needed to complete the adjustment

To attain this condition the nosepiece should either be purchased together with the microscope, or, if purchased subsequently, the Objectives forwhieh it is required should be sent to us for adaptation.
