A form of ultraviolet microscope of the refracting type is described in which the source of radiation is a spark gap between fixed or rotating electrodes and the objectives are normally monochromats. The microscope is horizontal, thus avoiding the use of a mirror, and the fine motion mechanism responds to movements of 0.10 micron. Phase contrast may be

The microscope and endodontics
Dental Clinics of North America, 2004The incorporation of the microscope in clinical endodontics has had profound effects on the way endodontics is done and has changed the field fundamentally. This article outlines the key prerequisites for the use of the microscope in nonsurgical endodontic procedures, discusses which procedures benefit from using the microscope, and addresses the issue

The operating microscope has transformed the surgery of glaucoma from a hit and miss affair to a very precise art. This is not to say that adult glaucoma surgery cannot be undertaken without sophisticated aids. Of course, it can, but as our understanding of the underlying mechanisms of the glaucoma improves, so do the methods of dealing with it.

Microscopes and Microinstruments
Hand Clinics, 1985This article outlines the basic physical principles of the operating microscope; in addition, it provides up-to-date, "state of the art" information of microinstruments.

Variable contrast in the image of non-uniform objects is obtained by polarizing orthogonally the deviated and undeviated bundles of light due to diffraction by the object. Advantage is taken of this orthogonality of polarization to effect variable phase difference between, and variable amplitude ratio of the deviated and undeviated bundles.
