WM6-BD Industrial Inspection Microscope Brightfield/Darkfield

The WM6-BD Industrial Inspection Microscope is equipped with a large travel mechanical stage, Epi-illuminator, long working distance brightfield and darkfield Infinity Plan Achromat objectives, wide field eyepieces with clear image quality and contrast.

Designed and developed for the semiconductor industry, wafer manufacturing, electronic industry, metallurgical industry and used as a high-end industrial microscope. Brightfield, darkfield, polarizing and differential interference contrast (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 moulds.
