Page 3: Description Of Components
Stereoscopic microscopes are used for viewing 3-dimensional objects, inspection or assembly of small parts, and for dissection of biological specimen. They provide an upright, unreversed image which permits easy manipulation of the object being viewed while looking through the microscope. They are designed for viewing solid objects at low magnification, but they will also permit viewing of some transparent specimen slides. - Page 4 9. STAGE CLIPS: Two locked-on clips hold specimen slide inplace on stage plate. 10. STAGE PLATES: Frosted stage is generally used for viewing transparent specimen and the black and white stage plate for viewing opaque specimens. 11. STAGE PLATE LOCKING SET SCREW: Locks 80mm stage plate into recesses of microscope base. 12.
- Page 5 Incidental illumination can be used with either frosted glass plate or black/white plastic stage plate. Transmitted and incidental illumination combined can provide extra illumination for certain objects where additional top illumination will enhance the object being viewed. NOTE: THE TRANSMITTED LIGHT POSITION REQUIRES USE OF BLUE FILTER AND FROSTED GLASS STAGE PLATE.
