Upright Microscope or Inverted Microscope: Which One to Buy?
An upright metallurgical microscope produces an erect image during observation, which greatly facilitates viewing and identification. Besides analyzing and identifying metal specimens with a height of 20–30 mm, it conforms to people's viewing habits and is widely used for transparent, translucent and opaque substances. It delivers excellent imaging results for observation targets ranging from 3 μm to 20 μm, such as surface structures and traces on metallic ceramics, electronic chips, printed circuits, LCD substrates, thin films, fibers, granular materials and coatings. Moreover, the optional camera system can be easily connected to a display and a computer for real-time and static image viewing, saving, editing and printing. Combined with supporting software, it meets professional requirements in metallography, measurement and interactive teaching.
The inverted metallurgical microscope adopts planar optical imaging to identify and analyze the microstructure of various metals and alloys. It is an essential instrument for metallographic research in metal physics. It is widely used in factories and laboratories for casting quality inspection, raw material testing, and metallographic microstructure analysis of materials after processing, providing intuitive analytical results. It is key equipment for quality identification and analysis in casting, smelting and heat treatment within mining, metallurgy, manufacturing and mechanical processing industries. In recent years, the microelectronics industry requires high-magnification planar microscopy to support chip production. Therefore, metallurgical microscopes have been introduced into this field and continuously optimized to meet special industrial demands.
For an inverted metallurgical microscope, the observation surface of the specimen faces downwards and aligns with the stage surface. The objective lens is placed under the stage and looks upward. This configuration is not limited by specimen height. It is easy to operate, with a compact and elegant structure. The inverted metallurgical microscope has a large base support area and a low center of gravity for stable and reliable operation. The eyepiece tilts at 45° relative to the supporting surface for comfortable observation.
