Capturing Minute Images Using Teaching Microscopes with Digital Cameras
Teaching microscopes are incredibly useful in classroom instruction, particularly because they are designed to assist in teaching and learning at the same time. Most teaching microscope models, for example, are equipped with dual heads to allow two users to view the specimen at the same time. However, this type of instrument can be improved with the addition of a digital camera.
Viewing images with teaching microscopes
There are several types of teaching microscopes, each one utilizing different applications. The choice of which one to use will depend on the requirement. A dark field teaching microscope, for example, may be used instead of a bright field microscope if higher contrast is preferred. With a digital camera attachment, a teaching microscope can do so much more.
Using digital cameras with teaching microscopes
Digital cameras allow high resolution capture of images, which makes them the perfect tools to use for viewing specimen with optical microscopy. Some of the most common teaching microscopes are equipped with two sets of eyepieces – one for the student and another for the teacher. Or, it may also be used by two students simultaneously.
For lectures, prepared slides may be viewed by the class again and again, provided the slides are prepared in the appropriate manner. However, some specimens are just naturally difficult to preserve. Live specimen and organic matter, for example, can be quite difficult to capture because specimens tend to be altered through exposure to temperature, air or other contaminants.
To ensure that these images are captured, a digital camera may be used. Images can then be viewed in the future and used by more individuals. Not only that, a digital camera can be used to store images. Many of today’s digital cameras have storage capacities that can keep hundreds of images which are easy to retrieve at any time.
An advantage of this is that images can be stored safely without altering them in any way. Images can also be edited for presentations or lectures. Since storage is not a problem, images can also be sent or shared through e-mails.
Optimizing images
An advantage of teaching microscopes with digital imaging cameras is that they have the capability of taking pictures at high resolutions, compared to regular cameras. However, a digital camera can only be as good as its ability to produce sharp, crisp images. A 1 megapixel or less digital camera, for example, will probably produce a decent picture of a specimen like blood cells and tissue samples but a 2 megapixel camera can show so much more. You will probably notice the difference when the image is enlarged. Higher megapixel digital cameras will produce fewer picture distortions compared to low megapixel cameras.
If image optimization is a concern, you can push technology further and use digital teaching microscopes. Microscopes with standard optical capability will usually provide good image quality but digital microscopes can show so much more. This makes them an excellent choice for clinical, laboratory and research applications. As teaching microscopes, digital microscopes offer a more sophisticated way of viewing specimens, thanks to its capability to produce high resolution images compared to standard microscopy. Furthermore, digital microscopes also allow users a variety of functions that are not available in standard microscopes, allowing users to manipulate the image.
However, when using digital teaching microscopes with digital cameras, remember that the image captured will only be as good as the lens that takes them. Using a low quality optical lens and a high resolution digital camera or vice versa will result to a poorly taken image. If you must use a digital teaching microscope with a digital camera, make sure they have the same capability.
Areas of application for teaching microscopes with digital cameras
When you have this kind of imaging capability, it would be a shame not to maximize its use. This type of setup is often too sophisticated for basic home or amateur use, although it doesn’t make it irrelevant. However, for serious hobbyists, researchers and scientists will find the capability of the teaching microscope and a digital camera a perfect fit for their needs. Some areas of application where teaching microscopes with digital cameras may be used include:
Health and medicine
For diagnostics and observation of specimens, a teaching microscope with a digital camera can be an excellent tool to use. Whether specimens are live or stained, users can observe and capture images effectively.
Natural science
Biological science is often a field that makes use of teaching microscopes with digital cameras. Live specimens are often difficult to prepare on slides for observation so by capturing images on the camera, they become much easier to store. This is particularly helpful if the specimen is rare or easily destroyed.
Forensic science
Forensic science often deals with some of the most extremely fragile materials such as organic matter. During lectures or presentations, a teaching microscope with a digital camera can observe and present images more conveniently than standard microscopy.
