Aligning the Condenser on a Biological Microscope

Biological microscopes are excellent for research, schools, and laboratories. The condenser should always be kept lint and fingerprint free for the clearest image. To clean the condenser it is best to remove it from the stage with a small screwdriver.

Once the condenser is unscrewed you can clean it and recenter it for optimal viewing. The center of the condenser is indicated with small perforated dots to help the end user align the condenser with the optical axis. If the sub-stage iris is also attached, which is fairly common with biological microscopes, then centering can be achieved by aligning the microscope objective on a low setting.

The sub-stage iris diaphragm should allow for a specific level of light to enter through the condenser thus illuminating the specimen and avoid over exposure. This will ensure proper exposure and resolution of your image and help ensure quality image and video every time you use your OMAX microscope. 

Brightfield Illumination Microscopy

The great thing about purchasing a bright-field microscope from MicroscopeNet is that it has a built in illumination that will directly reflect light onto the slide. Bright-field microscopes are great for observing stained samples that absorb larger areas of light. They are also excellent for observing naturally stained samples that allow a lot of light to reflect through.

The total bright-field system utilizes light from an lower source that allows the user to view magnified objects through an ocular lens. The condenser lens below the stage will direct the light through the specimen, making for a highly detailed image. This form of microscopy is best  for microbiology and botany.
