Abstract

Telemicroscope has a sample -holder plate rotatable about vertical axis of its column and veretically translatable with column, and balance microhardness matter. Upper part of microscope is protected by sealed vessel closed at lower end by closure consisting of replaceable plate of quartz; seal for column of plate through closure is an Hg-sealed joint; seal for durometer diamond is a flexible bellows fixed to closure.
