Introduction
BM-SG12BD transmission and reflection microscope (bright/dark field) is developed to meet the needs of the semiconductor industry, silicon wafer manufacturing industry, electronic information industry, and metallurgical industry. As a transmission and reflection microscope user, you can experience its super performance when using it, and it can be widely used. Applied to the detection of grease, semiconductors, FPD, circuit packaging, circuit substrates, materials, castings/metal/ceramic components, and precision molds.
This instrument adopts two forms of illumination: epi-illumination and transmission. Under epi-illumination, light and dark field observation, DIC observation, and polarized light observation can be performed. Brightfield observation under transmitted light. The stable and high-quality optical system makes the image clearer and the contrast better. Ergonomic design makes you feel comfortable and relaxed while working.
