Compound Light Microscopes are often used for brightfield microscopy activities. There is a great selection of these kinds of microscopes. Any microscope enthusiast knows that there are differences among the darkfield microscope, the fluorescence microscope, the phase contrast microscope and the polarized light microscope. The whole time we all thought that after seeing one microscope, you’ve seen them all.

What is a Brighfield Microscope?
To make it easier for us, let us limit the description of brightfield microscopes to compound light microscopes. There is a wide scope of bright light which is directly used without the manipulation of the user. This then includes those low power dissecting and stereoscopic microscope. However, the microscope enthusiast know that these aren’t brightfield microscopes.

To make the definition easier, it is important to remember that brightfield microscopes get its light from underneath. Therefore, microscopes having those halogen microscope bulb under the sample’s stage which can focus the light on the condenser are said to be microscopes perfect for brightfield microscopy.

The better the quality of the compound microscope, the brighter the condenser light. This is proven in the Koehler field diaphragm which is often used to focus the light on the sample that Is to be examined. The correct illumination of the specimen in brightfield microscopes is very important in order to get the illumination that is needed for the study.

Simple Colored Filters
The simple colored filters of brightfield microscopes are important in inserting these to the light path. To understand the various techniques involving in the microscopic process of this kind, the enthusiast can look at this as something that it is not. Brightfield microscope techniques are different from the other microscopy techniques.

Take for example, brightfield microscopes manipulate the light source through the disc diaphragm that is inserted in the light path. This illuminates the specimen with a light that is scattered. The brightfield microscope manipulates the light and creates a cone-shape that is the phase annulus ring which fills up the contrast condenser of the microscope. The light proceeds to the center of the phase disk in the aperature plane of the contraption.

This process changes the lighting technique of the brighfield microscope and the phase of the lighting for the samples because of the refractive index that often varies. This step shifts into a difference of contrast viewing. Take for example, with the fluorescence microscope, the light is used in order for the sample to excite the light that came from the original source. In polarized light microscopes, the original light source is the microscope bulb and it merely passes through the simple colored filters that have been polarized.

Afterwards, the transmitted light gets polarized, it passes through the filter that is termed as the analyzer. This is the second polarizer that is quite helpful in identifying and studying the samples under the brightfield microscope even further. The samples can be rotated on the stage and each angle can be covered because of this.

Basically, the brightfield microscope gets its light source from the bulb. This collects the light in the base and with the focus on the right Koehler illumination, this is transmitted into the samples on the slides of the microscope.

Portable Brightfield Microscopes
This remarkable and new portable kinds of brightfield microscopes has the features and capabilities of the full sized version of the microscope. The advantage is that it is more lightweight and is completely hand-sized making it portable. This is ideal for field work and forensics involving mobile laboratory. These microscopes are engineered in Japan and it has a cast case and metal parts that are often ensured for rigorous field use.

Portable brightfield microscopes are powered by batteries and can last hours as long as they have been charged properly before use. It also comes with shoulder straps and carrying cases for portability.
