OLYMPUS PMG-2 INVERTED METALLURGICAL MICROSCOPE
The round black knob on the left hand side does turn freely and there are 5 markings on it, they are:
0 micro 10 / 20 / 75 / 15
WHEN WE PLUG IT ONTO THE OUTLET AND POWER IT UP IT LIGHTS UP FINE AS YOU CAN SEE FROM THE PICTURES BELOW, THAT'S THE EXTENT OF THE TESTING WE KNOW TO DO TO THIS OLYMPUS!
PLEASE FEEL FREE TO ASK US ANY SPECIFIC QUESTION OR TESTING AND WE WILL PERFORM IT!
We have no idea whether this works or not, it is being sold as a collectors item, it looks great and all the parts seem to be present, it also should work fine since it was sitting in storage for many years but since we do not have the technical expertise to test it, we are selling it under an as is, no return condition!
The lenses on this microscope are:
1 - Hl MPLAN 100 1.25 - OLYMPUS 400132
2 - MPLAN 100 0.90 - OLYMPUS 400622
3 - MPLAN 40 0.63 - OLYMPUS 405735
4 - MPLAN 10 0.25 - OLYMPUS 400548
5 - MPLAN 5 0.10 - OLYMPUS 400592

Microscopes come in two basic configurations: upright and inverted. Inverted microscopes are used to observe the specimen from below. They were first developed and used before the Second World War for research and analysis of metal materials such as iron and steel. With the advances made in biological research after the War, scientists started to use inverted microscopes for observing living cells.
Inverted metallurgical microscope (1954)
The design of current inverted metallurgical microscopes originated in the PMF microscope launched in 1954. Before the Second World War, Olympus marketed the PMC, PMD, and PME as metallurgical microscopes. However, these microscopes with horizontal optical axes and large-format dry plates as photosensitive materials during photography were not said to be particularly easy to use.
The PMF incorporated the following features:
· Easier observations as a horizontal surface is made simply by placing the the sample (polished metal surface) on the stage.
· Minimal camera shake as the camera equipment is in a low position on an inverted microscope.
· More comfortable operation as all the operational handles are located in easy-to-use positions.
· Easier phase contrast and polarization microscopy through the use of phase and polarizing plates.
· Compact and easy-to-use microscope with built-in light source.
Olympus then built on the PMF features to develop its inverted metallurgical microscopes further for research applications in metal surface observations or composition and research on ceramics, plastics, and other new materials.
In 1956, Olympus launched the ME Standard Inverted Microscope.
The company then launched the high-performance PMG in 1964, featuring an internal photographic light meter, followed by the PME in 1967.
The PMG2, PMG3, and PME3, which were developed out of the PMF, were then combined with the cutting-edge UIS optical system (infinity correction) to produce the GX Series.
Olympus launched the GX71/51 Series in 2001. The use of UIS optics resulted in bright, high-resolution imaging. With this series, a microscope system could be built to meet specific research objectives by combining various image-recording devices, such as a digital camera, film camera (large format or 35mm film), or video camera. This inverted metallurgical microscope series provided optimal optical performance for all imaging, including observations, digital imaging, and photographic film images. The GX41, launched in 2004, produced bright, high-resolution images, while providing excellent cost performance. This compact inverted metallurgical microscope featured UIS optics and was designed for testing metal samples, electronic components, or automotive parts.
