The HN-3203 upright metallographic microscope is suitable for microscopic observation of opaque samples. This instrument is equipped with a falling beam illuminator, an infinitely long flat field achromatic objective, a large field of view eyepiece, and a built-in polarizing observation device. It has the characteristics of beautiful appearance and easy operation, making it an ideal instrument for research in metallurgy, mineralogy, precision engineering, electronics, and other fields. Suitable for use in schools, scientific research, factories, and other departments.
Performance characteristics
▲ Adopting an infinite distance optical system and modular functional design.
Infinite long working distance flat field objective, with a large and clear field of view.
▲ Wide angle flat field eyepiece: Field of view diameter Ф 22mm.
▲ Coarse and micro coaxial focusing mechanism, adjustable coarse and micro elasticity, with limit locking device, micro grid value: 2 μ M.
▲ Built in switchable polarization observation device, polarizer can rotate 360 °.
The falling light source adopts a flip type 6V30W halogen light box, which is safe and convenient to replace the light bulb.
The three eyepiece cylinder allows for free switching between visual observation and micrography, with 100% light transmission during photography, making it suitable for capturing low light microscopic images.
