The Function of Microscope Lamps

You can see an object because of the light reflected by that object. You can see things all around you because these things are illuminated. It is just logical to suppose that if you need to look into a microscope to analyze your sample, you need to have light as well. Microscope lamps provide this essential requirement.

Microscope lamps have been around for centuries for they were extremely necessary to scientists then and now. But the microscope lamps in use then vary greatly from the microscope lamps of today. Now, most microscopes have inherent or inbuilt illumination systems. Before, however, scientists had to rely on stand alone illumination systems. And when there was no electricity for artificial light generation, scientists made do with paraffin oil lamps, limelight and other obsolete methods of illuminating a sample under a microscope.

Nowadays, microscope lamps have evolved greatly due to newer and better technologies. The development of these microscope lamps have just kept apace of developments in the field of microscopy.

One such development is obtaining pictures through the microscope. If you are a scientist who intends to write a paper on a certain resistant strain of a common bacteria, you would probably like to have pictures and even video clips of your subject. Seeing, after all, go over better than dry facts and figures. You’ll be glad to know that you can now do this.

With the use of microscope adapters, you can attach your still camera or video camera to your microscope and be able to capture your subject on film and tape. The task gets even easier because of the development of digital imaging technologies. You can now get high resolution pictures and videos of your microscope sample.

Another more important innovation in the field of microscopic imaging is probe microscopy which does away with the microscope lamps all together. A scanning probe microscope does not use lenses so there’s no need for illumination. What it uses instead is a scanning probe, the tip of which scans the surface of the sample line by line. The interaction with the surface of the sample returns a precise and fine-scale image.
