Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year more history here. The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope versus an electron microscope. The simplest optical microscope is the magnifying glass and is good to about ten times 10x magnification. Ocular eyepiece lens to look through.

The performance of your microscope optics directly affects the final quality of your products. Olympus OEM components seamlessly integrate into large systems to provide the exceptional optical quality you need to deliver a high-quality final product. With more than years of optical-mechanical, electronic, digital, and precision technology experience, Olympus works closely with engineers and equipment designers to assist them in selecting from a broad range of off-the-shelf optics and OEM components, helping reduce product development time. Get in Touch. Olympus provides optical and mechanical data to assist in the integration of Olympus components into final product designs. Custom objective lenses and optical assemblies are available when design requirements extend beyond off-the-shelf components. Olympus offers infinity-corrected objective lenses for a variety of optical-mechanical systems.

Before exploring the parts of a compound microscope , you should probably understand that the compound light microscope is more complicated than just a microscope with more than one lens. First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens that cannot be seen by the naked eye. Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens. Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes. Body tube Head : The body tube connects the eyepiece to the objective lenses. Arm: The arm connects the body tube to the base of the microscope.

Though modern microscopes can be high-tech, microscopes have existed for centuries — this brass optical microscope dates to , and was made in Munich, Germany. A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell , its nucleus, mitochondria , and other organelles. While the modern microscope has many parts, the most important pieces are its lenses. A simple light microscope manipulates how light enters the eye using a convex lens , where both sides of the lens are curved outwards. When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye. This makes the object look bigger than it actually is.

Microbiology, the branch of science that has so vastly extended and expanded our knowledge of the living world, owes its existence to Antony van Leeuwenhoek. In , with the aid of a crude microscope consisting of a biconcave lens enclosed in two metal plates, Leeuwenhoek introduced the world to the existence of microbial forms of life. Over the years, microscopes have evolved from the simple, single-lens instrument of Leeuwenhoek, with a magnification of , to the present-day electron microscopes capable of magnifications greater than , Microscopes are designated as either light microscopes or electron microscopes. The former use visible light or ultraviolet rays to illuminate specimens. They include brightfield, darkfield, phase-contrast, and fluorescent instruments.

Skip to content Skip to section navigation. As per the blog " Using a microscope with students with visual impairments ". As middle school and high school life science students are introduced to the light microscope, students who are visually impaired should also be taught the parts of the microscope and their functions.

One of the wonders of the scientific world is that so much of what goes on is invisible to the naked eye. Invented in by a Dutch optician named Zacharias Janssen, the compound or light microscope gives students and scientists a close-up view of tiny structures like cells and bacteria. Read on to find out more about microscope parts and how to use them. The eyepiece contains the ocular lens, which the user looks through to see the magnified specimen. The ocular lens has a magnification that can range from 5x to 30x, but 10x or 15x is the most common setting.
