Microscope technology has advanced tremendously since the first compound microscopes of the 1500’s. Confocal, electron, and dark field microscopes are some of the instruments now available that open a window into the form and function of the tiniest of the tiny of the physical world.
Compound microscopes are still the most common variety, and BioSurplus carries a wide variety of them from the best manufacturers, including Leica, Zeiss, Olympus and VWR. We also carry extremely sophisticated microscopes and offer unbeatable cost savings over new equipment pricing.
To help you navigate the many types of microscopes BioSurplus has in stock, we’ve produced a video and accompanying in-depth article for our website. In the video, BioSurplus Senior VP Fred Hill explains microscope basics, and provides an overview of the different types of instruments on the market.
For further information we invite you to read our article that features sections on inverted and upright compound microscopes, electron microscopes—including scanning probe, fluorescence and light microscopy—inverted microscopes, and compound light microscopes.
See below for a transcription of the video:
“A microscope is essentially a piece of instrumentation that is used to look at things that are too small for the eye to see. Almost all microscopes today are compound microscopes, which means that it’s a compound of the magnification of the eyepiece times the objective; most eyepieces are 10x.
“The objective can vary from 4 to 10 to 20 to 40 to sometimes even 100x. So what you do is you compound that magnification 10x times the eyepiece times 4x times the objective. So a compound microscope in that case would give you 40x final magnification.
“There are many different types of microscopes available from BioSurplus. The easiest one to use is an optical microscope of which BioSurplus has many, which just uses light waves. There are confocal microscopes which use light waves along with lasers to measure depths of substances that you are looking at. There are scanning electron microscopes. There are dark field microscopes. There are fluorescent microscopes. There are many different types of microscopes available and BioSurplus has most of these.”
