A trinocular synchronous microscope回收ed from an electronics factory. It has been tested and functions normally with no double images. It has been stored for a long time, so the inside is slightly dirty and needs to be cleaned. The integrated screen is somewhat aged. The configured camera might be a bit outdated. The digital display effect is average. Anyway, it’s just like the picture shows. If you like it, take it and clean it up; it should produce good results. Suitable for purchase by masters with certain hands-on ability. Beginners should skip it. To save everyone the trouble.
