Question

Difference between metallurgical and biological microscope

Answer 1

Metallurgical microscopes:

The Metallurgical microscopes can be used for metallurgical inspection, including metals, ceramics, and other materials. A microscope is an instrument that is used for producing a magnified image of a small object. And in metallurgical microscope usually is a reflection microscope with light coming from above. Either by an external light source from above or through the lens with beam splitters.

Biological microscope:

In biological microscope. The only light comes from beneath the stage. The Magnification is changed by revolving the nose piece so a new objective lens is in place. On the other side we can say, the biological microscope usually is a transmission microscope with light coming from below. 

Answer 2

Compound magnifying instruments are partitioned into two noteworthy classes relying upon the sort of test and the light path used to look at it. The typical biological magnifying lens is intended to look through the specimen, with the light sparkling up through the example - this is alluded to as diascopic brightening. The examples are thin and straightforward or translucent.

Opaque examples are analyzed with light from over the specimen that is reflected back - this is alluded to as episcopic enlightenment. These specimens are seen with the metallurgical magnifying lens in metallurgy, designing, producing and other mechanical applications.
