Metallurgy microscope Model NJF-120

Developed for research of the surface of a metal object, for example, the integrated circuit, miniaturized construction units, the NJF-120 finds various applications in materials technology, quality control, geology, mineralogy, building material or glass materials science. It can be used also for investigation of transparent objects in the biological, medical and chemical field. The NJF-120, characterized by its high optical, mechanical qualities and robustness, promises reliability and precision. With its complete accessories NJF-120 fulfills the requirements from professional applications in the broad spectrum.

 
 
 
 
 
 


Characteristics of the model NJF-120 as a professional microscope:

  • Equipped with plan objectives of infinite optics.
  • The objectives are corrected for the use without cover glass.
  • The plan objectives make a sharp picture both in the center and at the edge possible.
  • The characteristic of the infinite optics makes it possible that even with different mechanical length (distance between eyepieces and objectives) it can be focused. That means that other eyepieces can be used problem-free.
  • The wide field eyepiece of 10x with a embedded micro ensures not only a broad viewing but alos an easy optical measurement.
  • The coaxial operation for rough and micro-adjustment makes the work more comfortable.
  • The coaxial top illumination halogen lighting goes through die objectives for surface view.
  • The coaxial top illumination is equipped with centering mechanismus and insert possibility for filter.
