The initially known microscopes were simple yet functional. They normally consisted of a tube with the lenses mounted within, and adjustment knob to increase or lower the intention over the specimen for focusing, and a mirror under the simplistic stage to brighten the specimen with sunlight or candle.
Early microscopy supporters such as Anton van Leeuwenhoek relied mostly upon candlelight to illuminate the objects they were observing. The advances these early microscope users made were unusual, considering what they had to work with.

Microscope illumination has advanced greatly over the past fifty years. The first advance was electrical illumination. This was the gold pattern for illuminating the exemplary during microscopy.
A small light bulb was mounted on a swiveling base, so the user could aim the beam of light either directly into the observable thing or to the side for less light. This system became the staple of compound microscopes.
Stage lighting using a condenser was the next form of microscope illumination. A condenser has an iris that can manipulate the light to different levels of light so those faint objects were brought out to the viewer.
There are now obstructed light fixtures on microscopes, which can soften the light for easier eye relief. Peering into a microscope day after day, hour after hour can be very taxing on your eyes. Having softer microscope brilliance is a benefit for professional microscopy personnel.
