Optical Microscopy

The optical microscope, often referred to as the light microscope, is a type of microscope that commonly uses visible light and a system of lenses to magnify images of small objects. The Denver Microbeam Lab has two main optical light microscopes to help with geology and minerology.


Reflected Light Imaging

Transmitted Light Imaging

This microscope can be used for optical observations and imaging of samples. There is an attached camera at the top that is connected to a computer that is used to record and save images.
