Digital high power microscopes are the type of microscopes that are getting highly popular these days. They are special types of microscopes capable of bringing crisp fine images of the specimen under observation. There are certain applications that only high power microscopes can be used. And it follows that if regular microscopes are used, either the images produced are not totally accurate or there are absolutely no clear image produced at all.

High power microscopes are commonly used inside a biological laboratory setup. These microscopes are the ones most preferred when viewing live blood samples, fresh tissues, cells, and other microorganisms. High power microscopes, as its name suggests, is capable of magnifying specimens to as much as 1,000 times more than its original size. As such, it becomes very easy for users to study, analyze, and determine the present condition of the sample they are looking at.

Phase contrast microscopes are good examples of high power microscopes. These microscopes are best used in viewing unstained samples mounted on microscope slides. When a phase contrast microscope is used, the image produced can be made brighter, dimmer, or sharper with the contrast control knobs that are equipped with the device. With this microscope, there’s no need to stain samples at all. Phase contrast microscopes have a comprehensive lighting system that allows observers to see transparent samples even without treating them with dyes. This feat, however, is impossible with regular tabletop microscopes. Only digital high power microscope such as a phase contrast microscope can do it.

Dry blood, on the other hand, is a different scenario, although it may be viewed with a phase contrast microscope as well. However, even the most common high power compound microscope that uses regular light to illuminate its sample should be sufficient. Dry blood samples are good for educational and training purposes. And for a more advanced viewing exercise, teachers can ask their students to observe dry blood samples through a dark field illumination system, rather than the most commonly used bright field microscopy.

Consequently, this brings forward the other type of high power microscope - the dark field microscope. Although this can be used to view unstained samples like a phase contrast microscope, the principle that makes the device works is very much different from it. Dark field microscopes are a little more similar to a bright field microscope than phase contrast microscopes. But instead of producing the specimen against white background like bright field microscopes do, the sample can be seen against a black background.

And it is made possible with the high power lenses that are equipped with the dark field microscope. A dark field microscope is created with a dark field condenser and its main job is to light the specimen from its sides. It is different from regular microscopes because regular microscopes are normally lighting its specimens from its bottom. Dark field microscopes are best used with blood samples as well. And this is because it is capable of producing the sample’s more intricate details, which can’t be seen normally using a regular low power microscope.

High power microscopes, being complex in nature, are usually binocular. Most of them are compound microscopes that use the common principle of light to illuminate the sample under observation. There are also units equipped with only one eyepiece. These are called monocular microscopes. Monocular microscopes may also be high power microscopes. The observed image, however, maybe a little limited when compared with a binocular high power microscope.

But what makes digital high power microscope at par with the current times is its capability to be interfaced with a computer system and a digital camera. Most high power microscopes are manufactured with trinocular port. Aside from the binocular eyepieces, an additional port is attached to it so that a digital camera can be interfaced with the microscope’s system. As a result, the images can be seen through a compatible monitor set. Observers find this more convenient, as they don’t need to peep through the eyepiece just to study the specimen.

But that’s not all what a digital high power microscope can do. Because it is digital, it can print images directly to a still or video printer for easier filing. Hard copies of certain specimens are essential. This is especially true when the microscope is used to diagnose certain diseases. With quality printouts directly coming from the microscopes, doctors will find it easier to explain to patients what their diseases are. In the same way, doctors could easily refer to the images for the patient’s future treatments.
