Transflective Metallurgical Microscope, LW300LJT

 The LW300LJT transflective metallographic microscope uses an advanced infinity optical system for superior imaging results. It can be used for bright field observation and simple polarized light observation. It is an ideal instrument for semiconductor inspection, circuit packaging, circuit board and materials. Suitable for microscopic observation of opaque or transparent objects. The instrument is equipped with an epi-illumination and transmission illumination system, an infinity long-range flat-field achromatic objective lens (without a cover glass), a large-field eyepiece and a built-in polarizing observation device, which have the characteristics of clear image, good contrast, beautiful appearance and convenient operation. It is an ideal instrument for research in biology, metallography, mineralogy, precision engineering, electronics, etc. It is suitable for use in schools, scientific research, factories and other departments. It is also widely used in the textile industry to see the structure and characteristics of fibers in fabrics.
