IM-5000 Metallographic Microscopes

Optical microscopy using metallographic microscopes is a widely used technique for analyzing metallographic specimens. The typical magnification range for optical microscopes is 50 to 1000X, however higher magnifications are possible with specialized oil immersion lenses. The standard resolution for optical microscopes using air immersion lenses is between 0.5 to 10 micron. Optical microscopes use a number of different optical techniques to reveal specific microstructural features, including the following illumination techniques: brightfield, darkfield, oblique (stereo) and differential interference contrast (DIC).

Stereo Metallographic Microscopes (ZMS0745T)

The ZMS0745T trinocular stereo microscope has an optical design for enhancing reproduction and true color imaging of the image.

The ZMS0745T stereo microscope has a magnification range of 7X to approximately 45X and is ideal for low magnification documentation of the metallographic specimen prior to polishing and grinding. It is also very useful for measuring cracks, weld penentration depth and other topographical features.

Feature Specification Eyepiece 10X Total magnification 7-45X Zoom objective magnification 0.7X ~ 4.5X Trinocular eyetubes Inclined 45 degrees from main body (360 degree rotation) Diopter adjustment +/- 6 degrees Interpupillary adjustment 2” ~3” (52 ~ 76 mm) Focus range 100 mm (50 mm post) Stage size 3” (76 mm) Distance from post to center of focus 5” (125 mm)
