What is a metallographic microscope

The metallographic microscope system organically combines a traditional optical microscope with a computer (digital camera) through photoelectric conversion. Not only can microscopic observations be made on the eyepiece, but also real-time dynamic images can be observed on the computer (digital camera) display screen. , computer-based metallographic microscope and can edit, save, and print the required pictures.

A metallographic microscope is mainly composed of an optical system and an illumination system. The optical system includes eyepieces, relay systems, and objectives.

Typical applications include grain size, inclusion counting, layer thickness assessment and phase determination. Some models have special facilities, such as darkfield and DIC, that provide improved observation techniques for certain classes of specimens.

Metallographic microscopes all have polarized light capabilities, a range of filters, and camera ports for photography and image analysis; some upright models have both incident and transmitted light for use with more transparent materials.

Performance of NJF-120A series metallographic microscope

  • 无限远平场光学系统和长工作距离物镜提供卓越的光学性能。
  • Ultra-low front-mounted coarse and micro-movement operations reduce user fatigue and make the relationship between man and machine closer.
  • Plug-in light bulb replacement device makes the replacement of light bulbs simpler, safer, and more reliable.
  • It can be used to observe and detect various PCB circuit boards, LCD liquid crystal display panels, and metallographic structures. Its comfortable and exquisite mirror structure and easy and fast operation methods are ideal for industrial optical testing instruments in industrial and mining enterprises and metallographic teaching instruments in schools. First choice.
