Ergonomics and Efficiency


Ease and Comfort Operation

Brightfield/Darkfield Switching Lever
GX51 is available for brightfield, darkfield, DIC, and simple polarization observations. Switching between brightfield and darkfield is simple and easy with an ergonomic efficiency. Operator controls are located in front of the frame for ease of operation and user comfort when inspecting large numbers of samples.

Enhanced Efficiency Through Motorization

The use of motorized components can save time and cut costs when large quantities of samples require analysis A single handset is available to quickly control the rotation of objectives. For higher levels of speed and analysis, Stream Image Analysis Software is will manage additional components such as the motorized filter wheel and automated scanning stages.


Excellent Image Clarity and Superb Resolution


Wide Variety of Choices for Superior Imaging Performance

UIS2 optics delivers bright, sharp, high-resolution images suitable for all observation methods: brightfield, darkfield, differential interference contrast, polarization, and fluorescence. Designed with specific wave front aberration controls and specialty coatings for color fidelity, UIS2 optics ensure images are true to form and highly resolved.

Software Solution


Built to Easily Work with Digital Cameras and Image Analysis Software

Our full line of digital cameras provide high resolution viewing and fast image transfer while our advanced OLYMPUS Image Analysis Software empowers users and provides all the tools required for today’s most complex metallurgical requirements. Choose from Extended Measurements, Standard Metallography and Advanced Metallography application specific modules (over a dozen application specific routines) and automatically populate data and create reports in compliance with the most popular ASTM and ISO specifications, all with just a few clicks of the mouse.





Intermediate Modules

In addition to the built-in front camera port, intermediate tubes such as the IX-ATU with trinocular tube or the GX-SPU side port allows the use of an additional cameras.

Transmitted Light Illuminator

A transmitted light illuminator can be attached to the back of the microscope body, enabling observation of transparent specimens and powders.
