The Digital Microscope – The Microscope Without an Eyepiece

A microscope without an eyepiece is still a microscope. Call it the digital microscope. This unusual piece of microscopy relies on a sensor to give a magnified view of the specimen displayed on the monitor.

Microscopes Have Gone Digital

It is a digital world and microscopes were not spared with the addition of the digital microscope to the stable of microscopes with add-on features. Basically, microscopes have the same parts but the digital camera goes off tangent with a built-in CCD camera.

A CCD or charge-coupled device is a sensor that records images of plant and animal tissues, or microbes that is shown on the monitor screen of the computer via the use of the PC’s USB port. Microscope The image can be stored in the computer’s hard drive for later reference.

The digital microscope uses transmitted light, fluorescence, and phase content to observe plant and animal tissues and microbes. Using the magnification selector, students and scientific or researchers can view the image 25x, 100x, 200x, 400x or 1,000x the original size of the object and the larger the monitor, the larger the on-screen magnification.

In other microscopes, magnification has to be determined by multiplying the magnification capacity of the objective lens by the magnification capacity of the eye piece. Image magnification is one consideration when buying a microscope apart from its use – for hobbies, research, and school laboratories.

Added Advantages

Already sophisticated as it is, work is still being done to improve the digital microscope to the next level. Currently, the microscope offers the best image visibility, and the use of the monitor allows several persons to view the samples at the same time allowing them to observe any changes at the same time. This makes the microscope an ideal educational and research tool.

However, the digital microscope has limitations. Since the monitor screen is essential to accurate magnification, one needs a ten foot screen for an accurate magnification of 200x. The idea centers on the actual magnification offered by the microscope including the expansion size facilitated by the screen on hand.

However, this limitation does not discourage scientific or school research and hobbyists. The microscope is not bulky and can be toted along for onsite research. With a laptop computer, and a USB, one can get to work without any problem. You will be looking at a USB version of digital microscopy. The USB is attached directly to the laptop’s USB port and the images can be recorded, saved, and filed the usual way you store files in your computer. It’s digital all the way.

Great Use for Hobbies, etc.

The USB digital microscope is useful for studying flat objects. Coin collectors can study every crack and blurred images of old coins with the microscope. Banknotes and old documents can easily be magnified too. Take note; whatever can be studied under the lens of the stereo microscope, can be examined digitally. If you want the regular instrument, just don’t demand a digital microscope with an eyepiece. There’s none.
