The flywheel in newer models is often integrated inside the microtome casing. The typical cut thickness for a rotary microtome is between 1 and 60 μm. For hard materials, such as a sample embedded in a synthetic resin, this design of microtome can allow good "semi-thin" sections with a thickness of as low as 0.5 μm.
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.

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 scaled-up version of the Questar 3.5" with the integrated Control Box, the Questar Seven, with a nominal 2400mm focal length, has twice the aperture and four times the light gathering power of the 3.5. The form-factor is similar to the 3.5 Duplex model as the barrel is separate but attaches to the base of the clock drive assembly.
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]
Microscope slides are thin strips used to hold items under a microscope. Examples of glassware used for measurements include: Graduated cylinders are thin and tall cylindrical containers used for volumetric measurements. Volumetric flasks are for measuring a specific volume of fluid.
