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.

A compound microscope is a microscope that uses multiple lenses to enlarge the image of a sample. Typically, a compound microscope is used for viewing samples at high magnification 40 - x , which is achieved by the combined effect of two sets of lenses: the ocular lens in the eyepiece and the objective lenses close to the sample.

The functional parts of the microscope

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. Objective lens, closest to the object. Before purchasing or using a microscope, it is important to know the functions of each part.

The main components of light microscopes are: eyepiece, lens tube, objective revolver, stage, table, condenser, fine focus, coarse focus, luminous-field diaphragm, light source, base. An eyepiece is that part of an optical system, which is directed to the viewer. It is a construction of at least one or more lenses. The function of the eyepiece in a microscope is to convert the real- enlarged-intermediate-image from the objective into an enlarged-virtual-image. In an ideal case, the exit pupil is not larger, so that the complete pencil of rays can enter the eye. Microscopes normally operate with a lens tube length of millimeters. Newer and especially professional microscopes use a longer lens tube.

A microscope is one of the invaluable tools in the laboratory setting. It is used to observe things that cannot be seen by the naked eye. From a simple microscope, there are now most advanced versions which perform a more complex function. Microscopes are specially created to magnify the image of the subject being studied. This exercise is created to be used in homes and schools.

Microscopy

The optical microscope , also referred to as a light microscope , is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast. The object is placed on a stage and may be directly viewed through one or two eyepieces on the microscope. In high-power microscopes, both eyepieces typically show the same image, but with a stereo microscope , slightly different images are used to create a 3-D effect. A camera is typically used to capture the image micrograph. The sample can be lit in a variety of ways.

Basic parts of the microscope:. They are usually 10X or 15X power. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.

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.

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.
