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 travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm. The precision is such that better-quality instruments have measuring scales made from Invar to avoid misreadings due to thermal effects.
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 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 ...
The ultramicrotome is also used with its glass knife or an industrial grade diamond knife to cut survey sections prior to thin sectioning. These survey sections are generally 0.5 to 1 μm thick and are mounted on a glass slide and stained to locate areas of interest under a light microscope prior to thin sectioning for the TEM.
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 Foldscope is an optical microscope that can be assembled from simple components, including a sheet of paper and a lens. It was created by Manu Prakash and designed to cost less than one USD to build. It is a part of the "frugal science" movement which aims to make cheap and easy tools available for scientific use in the developing world. [2]
