Metallographic microscopes are a type of optical microscope that utilizes reflected light. They differ from typical biological microscopes in their principle of operation, using vertical illumination where light is directed through a beam splitter into the microscope tube below the eyepiece. These microscopes are used for high-magnification observation of opaque objects, primarily in metallurgy and other materials that do not transmit light.

a. Upright Metallographic Microscopes

  • Positioned with the objective above the specimen, these are the most common type.
  • They feature an illumination system above the stage, directing light through the objective onto the sample and then reflected into the eyepiece.
  • They can be equipped with a pillar stand or a typical base stand, offering stability for observing smaller specimens or flexibility for different-sized samples.

b. Inverted Metallographic Microscopes

  • With the objective beneath the specimen, they can accommodate larger samples.
  • The illumination system is mounted beneath the stage, allowing light to pass through the objective, illuminate the sample, and reflect into the eyepiece.
  • They excel in observing larger samples that are not visible with upright microscopes, making them ideal for various engineering and manufacturing applications, such as studying fractures or corrosion.
  • They integrate multiple technologies for observing metal surfaces and structures after heat treatment, combining optical microscopy, photoelectric conversion, and computer image processing.
  • Compact design with aesthetic appeal, facilitating convenient use and providing clear imaging and a wide field of view, meeting ergonomic standards for prolonged operation.
  • Well-designed with a large base area for stability and low center of gravity, ensuring steady placement during use.
  • They are used for identifying and studying the structure of various metals, alloys, and non-metallic materials, including surface conditions of integrated circuits and micro-particles.
