From there the tissue can be mounted on a microscope slide, stained with appropriate aqueous dye(s) after removal of the paraffin, and examined using a light microscope. [12] Frozen section procedure: water-rich tissues are hardened by freezing and cut in the frozen state with a freezing microtome or microtome-cryostat; sections are stained and ...
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
A set of standard 75 by 25 mm microscope slides. The white area can be written on to label the slide. A microscope slide (top) and a cover slip (bottom) A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope.
A 10× achromatic triplet jewellers' loupe. Jewellers typically use a monocular, handheld loupe to magnify gemstones and other jewelry that they wish to inspect. [4] A 10× magnification is good to use for inspecting jewelry and hallmarks [4] and is the Gemological Institute of America's standard for grading diamond clarity.

A traveling microscope. E—eyepiece, O—objective, K—knob for focusing, V—vernier, R—rails, S—screw for fine position adjustment. A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm.
A 200 kV version of this microscope was delivered to the Orsay STEM laboratory near Paris in 2010 and many other labs since. It is able to reach 0.5 Å resolution. Nion went on to develop a monochromated STEM, with the first delivery to Arizona State University in 2013 and subsequent deliveries to Rutgers University, Daresbury SuperSTEM, [ 9 ...
To enable several people to use them at once, each microscope is able to project images with a built-in projector. [6] The Foldscope is designed to be assembled by the end user, and hence is color-coded to help with the assembly. [5] Each unit costs less than one US dollar to build, with estimates varying from 50 cents to 97 cents. [5] [6]
