WM8 Multifunctional Measuring Microscope

The WM8 Multifunctional Measuring Microscope is equipped with a reflected light illuminator, auxiliary focusing function for precise height measurements, long working distance brightfield and darkfield Infinity Plan Achromat or brightfield Plan Apochromat objectives, widefield eyepieces with clear image quality and contrast.

Developed and aimed at the semiconductor industry, wafer manufacturing, electronic device industry, metallurgical industry and used as a high-end industrial microscope. Brightfield, darkfield, polarizing and Nomarski DIC observations can all be utilized. It is widely used in factories, research and educational institutions to identify and analyze wafers, FPD, circuit substrates and precision molds.
