A brief introduction
The HN-3230BD upright light and dark field of view transparent and reflective metallographic microscope is a multi-purpose industrial inspection optical instrument, equipped with light/dark field objective lenses, large field of view eyepieces, and polarized observation devices. The transparent and reflective lighting adopts the "Kohler" lighting system, with a clear field of view. It can be used for the inspection of semiconductor silicon chips, LCD substrates, circuit boards, solid powders, and other transparent or opaque industrial samples. It is an ideal instrument for research in biology, metallurgy, mineralogy, precision engineering, electronic engineering, and other fields
Performance characteristics
▲ Adopting an infinite distance optical system and modular functional design.
▲ Long working distance light/dark field 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 upper light source adopts a flip over 12V50W halogen light box, which is safe and convenient to replace the light bulb. The lower light source adopts a 12V30W halogen light and is equipped with a heat sink.
The three eyepiece cylinder allows for free switching between visual observation and micrography, with 100% light transmission during photography, making it suitable for capturing dark field micrographs.
