Product details
TNJ-18D series inverted metallographic microscopeMainly used for identifying and analyzing the internal structure and organization of metals, it is an important tool for studying metallography in metal physics. The optional photography device of this instrument can take integer magnification photos required for metallographic spectra, and is suitable for factories, mining enterprises, universities, and scientific research departments.
TNJ-18D series inverted metallographic microscope
Performance characteristics
Equipped with a large field eyepiece and a long-distance flat field achromatic objective lens (without cover glass), the field of view is large and clear.
Coarse and micro coaxial focusing mechanism, adjustable coarse and micro elasticity, equipped with locking and limiting devices, micro grid value: 2 μ m.
6V20W halogen lamp with adjustable brightness.
When selecting a rotating eyepiece, it can freely switch between normal observation and polarized observation, and can perform 100% transparent photography.
