Tokyo – Nikon Corporation (Michio Kariya, President) is pleased to introduce the ECLIPSE MA200, a new-type inverted metallurgical microscope for the material science world that enables microstructural observation, and evaluation and analysis of a variety of materials, including metals, ceramics and polymers. The uniquely designed cube-shaped microscope provides solutions for research and development, and for inspection and quality assurance in the automotive and materials-related industries.

Product concept
This metallurgical microscope is categorized as an industrial microscope.
It is used for visual inspection of industrial materials such as metals,
ceramics and polymers.
The ECLIPSE MA200 has been developed as a replacement model for the currently
available inverted microscopes TME300 and TME200, and a higher-level version
of the mini inverted metallurgical microscope ECLIPSE MA100, which was released
in November 2006.
The ECLIPSE MA200 boasts improved operation, such as with the objective lens,
sample visibility and other operations. Furthermore, digital imaging capabilities
have been enhanced by parameter output for image capture and analysis.
