An optical microscope, which is one of the oldest and simplest microscopes used today. It has a CCD (charged-coupled device) camera built in and used for the magnified viewing of specimens and samples. It falls under the category of compound microscope, which means it has at least two lenses and gives you high resolution.
With this particular type of optical microscope, it could be connected to a computer to enable the images they producing to be saved onto a hard drive.This makes it easy to inspect the images later or have them displayed on a monitor so many people can view the specimen at the same time. Using a combination of technologies, a digital microscope plays a crucial role in education and in research.
Most of these microscopes are built with the same foundation as other light or optical microscopes. The laboratory technician would place a specimen beneath an object lens. There are many useful references regarding laser services at http://einstinc.com/wpccategories/laser-light-sources/.
To make it easier to see the specimen an attached light source is used. The specimen is magnified by the object lens and the image is brought into focus within the digital microscope tube. With a regular stereo compound microscope, there would be an eyepiece. It is called the ocular lens.
This lens would magnify the specimen again so the one looking at it could see it. A digital microscope uses a digital camera to focus the image instead of with an eyepiece.
For much of the magnification of a digital microscope they are dependent on the optics from the objective lens. How much magnification you can get with a digital microscope depends on the monitor size and the resolution of the camera used. Digital zoom, or magnification, manipulates this image in order to make it larger.
Most digital microscopes have a high-resolution camera so the images they produce do not appear blocky. The images can appear blocky when the tiny points of color making up the image increase in size as they are magnified.
