• 50W Koehler Vertical Illumination (Incident)
• 30W Koehler Illumination (Transmitted)
• Plan Epi Infinity Corrected Objectives

Full Koehler illumination is standard, powered by a 12V 50W halogen lamp for vertcial incident illumination. A separate transformer is included in its own case for the incident light. A Koehler 6V 30W halogen lamp built into the base provides transmitted illumnination. Both lamps include a useful auto-voltage sensor. Four filters are included: blue clear, green clear, neutral (ND 50), and polarizing, all of which have a diamater of 20mm with a 30mm metal mount.

The U0B200J has dioptric adjustment for convenient focusing of both eyes, and the eyepieces have an interpupillary adjustment range of 53-75 mm to adjust comfortably to the distance between your eyes. Additionally, the microscope is available in trinocular format with a beam splitter (80/20 trinocular port/eyepieces) so that you can operate the trinocular port and right eyetube simultaneously, if desired.

Metallographic microscopes are compound microscopes especially designed for observing the etched surface of a polished metal specimen. With both bright and darkfield microscope capability, these light microscopes meet the requirements of research and inspection in fields such as metallurgy, electronics, semi-conductors, and crystallography and are specially designed for the observation of metal objects.
