"In the boundaries of its current capacity, Metallograph
offers simplicity and very good production rates, excellent print quality and tight registration, novel structures, and good profit from modest utilization."
Laser Profilometer, Polarized Optical Microscope and inverted metallograph
Two kinds of microscopes are especially useful to materials researchers: the familiar upright microscope, in which the objective lenses are looking down on the sample and microscopes with upward-pointing objectives, such as a metallograph
. The latter design has two benefits.
Low-powered binoculars bench microscope or metallograph
scanning electron microscope
Its new Model SZH-LF stereo microscope is a hybrid product consisting of a stereo body and the oversized stage from the company's upright metallograph
In selecting a microscope, researchers in the materials sciences must choose between an inverted model, usually called a metallograph, or an upright.
With inverted microscopes and metallographs, the specimen rests with the flat, polished surface to be examined against the stage, which is perpendicular to the axis of the microscope.
of 34CrNiMo6 steel with different ratios of Al to N are shown in Figure 3 to reflect the evolutions of average grain size with the content of aluminum.
High-power, compound, reflected-light microscopes, known as metallographs
or metallurgical microscopes, serve a multitude of purposes in the failure-analysis lab.
To quantify the grain size, lineal intercept approach as suggested by ASTM  was applied based on the sample metallographs
as is shown in Figure 5.
Operators may choose from metallographs
, upright microscopes (with all modes of illumination) and stereo microscopes, all of which may export images to an image analysis system or closed-circuit television.
