NK-800 Upright series metallographic microscopeDetailed product description：

NK-800 upright series metallographic microscope

1. A series of metallographic microscopes for research, covering observation methods such as bright field, dark field, polarization, etc,
2. There are two lighting systems to choose from: transmission and reflection, equipped with a high-power transmission reflection dual path Kola lighting system,
3. Suitable for analyzing the internal organizational structure of materials in industrial and mining enterprises, universities, and research institutions;


Features:
Observation tube:
Articulated three eye observation tube, tilted at 300 degrees, comfortable and aesthetically pleasing. Pupil distance of 48-75mm, convenient for any observer to use. Eyepiece: EW10X ultra large field of view eyepiece, with a field of view of 22MM, making the area of the observed object larger and the search for targets easier. Adjustable visual acuity ensures system focus.
Converter: An inward facing objective lens converter makes specimen retrieval and placement more convenient, and can prevent hot air in the mouth from affecting lens observation. Stage: Rectangular double-layer activity platform, size 185X142MM, movement range 75X55MM, low position operation of handle, can reduce operator fatigue.
The 24V100W infinity flat field achromatic objective lens of the infinite illumination system provides high-quality optical imaging and ensures clear images.
Especially the 100X dry mirror
Polarization observation system, dark field observation system
