| A reliable microscope is an essence for effective diagnosis and health care. A microscope is required to visualize a living or dead organism in high magnification. A microscope allows to visualize a specimen, see the details of an object and determine the shape, size and even formation of that with a video time-lapse or a very high-speed mechanism. These specimen can be a cell, virus, bacteria, yeast, fungi, parasites, zebrafish, insects or part of tissue on a slide, either stained or unstained. The most common microscope for clinical labs, biological laboratory, veterinary colleges, biomedical research labs, microbiology teaching labs is a compound biological microscope. |  |
| Both upright and inverted biological microscopes are commonly used for the biology or clinical labs. The only difference, which makes a benefit of using inverted microscope over upright is that when you deal with liquid samples (like cell cultures) or a product such as MEMS or microfluidics that you cannot flip over. The rest stays the same as it follows the same principle of the light path and optical design. A regular upright biological microscope has 4x, 10x, 40x and 100x objective lenses and 10x eyepieces. This means you can expect a total magnification of 40x and 1000x. It is technically possible to increase this magnification via eyepieces and/or camera to 1500x or 2000x. Bioimager is proud to announce offering biological microscopes with 2500x, 3000x, 4500x, 5000x and even 10,000x. Contact us for details. |  |
| Beside brightfield imaging, in which the structure of organisms is seen in a bright background, we often need to use darkfield imaging in which the background is dark (or semi-dark) and the organism or micro-organism structures can be visualized. Very common applications in this regard are blood cells and bacteria. If you are in a hospital and need to determine if the observed bacterium is treponemes (causing syphilis) or leptospires (causing leptospirosis), darkfield imaging is a must to use. You need a microscope that has special condenser and objective lens for darkfield imaging. |  |
