A metallurgical microscope with an exceptional lightning orientation microscope which is used to view opaque objects. It is a high power microscope manufactured to identify, inspect and measure solid specimens. These microscopes are manufactured on the principle of reflected light microscopy and makes viewing of the objects though which light cannot pass easier. Micron's Cresta ZS 50i-MET is a high-performance inverted metallurgical microscope designed for the examination of opaque specimens such as metals, ceramics, and minerals. It utilizes an infinite optical system and reflected light illumination to provide high-contrast, high-resolution images of polished and etched samples. This model is widely regarded as one of the best metallurgical microscopes for materials science laboratories and industrial quality control. The binocular head is inclined at 30 degrees for comfortable viewing. The quadruple ball-bearing nosepiece holds a range of plan objectives.
