Hibiscus Pollen under the Microscope

This image of hibiscus pollen was captured by Harald K. Andersen in Steinberg, Norway. Andersen captured the image with a biological microscope at 150x magnification using darkfield microscopy. He then took a stack of 155 TIFF images and compiled them using image stacking software to obtain the image below.

Cerebellum under the Microscope

The cerebellum, also known as the "little brain" is a structure located at the back of the brain, underlying the occipital and temporal lobes of the cerebral cortex. Although the cerebellum accounts for approximately 10 percent of the brain's volume, it contains over 50 percent of the total number of neurons in the brain.

Historically, the cerebellum has been considered a motor structure, because cerebellar damage leads to impairments in motor control and posture and because the majority of the cerebellum's outputs lead to parts of the motor system. Motor commands are not initiated in the cerebellum, rather the cerebellum modifies the motor commands of the descending pathways to make movements more adaptive and accurate.

The cerebellum is involved in the following functions:
  • Coordination of voluntary movements
  • Maintenance of balance
  • Motor learning
  • Maintenance of posture
  • Cognitive functions
The images below of the cerebellum were captured using the Fein Optic RB30 lab microscope with the HDCAM4 high definition microscopy camera.

Stomach Fundic Region under the Microscope

The fundic region of the stomach is formed by the upper curvature region of the organ. The glands in this region are known as gastric or fundic glands and extend all the way to the muscularis mucosae. From three to seven glands open into the base of each gastric pit. Each gland has a fairly long, narrow neck and a short, wider base. At their base, the glands may divide into two or three branches which become slightly coiled. In the fundic region, almost the entire lamina propria (mucous membranes) are occupied by glands. The lamina of the glands are usually not identifiable and they usually appear more like cords of cells. The only "typical" lamina propria can be seen in the areas between the foveolae and around the bases of the glands.

The cross sections of the fundic region of the stomach shown below were captured using the RB30 lab microscope and a HD high definition microscopy camera.

Understanding Stereo Microscope Optics

There are two types of optical designs for stereo microscopes.
Each stereo microscope system has its advantages. Specifically, with the CMO system (a), because of the optical design, there is a capacity for much higher magnification and resolution. This design is most commonly used in research applications requiring both higher magnification and higher resolution (NA). This design results in a relatively flat field and does not generate a pronounced three dimensional image.

For the Greenough system, the primary advantage is that it provides a pronounced three dimensional image and is very useful for relatively low magnification and inspection of items with "depth". Because of the "V" design of the optical path (b), as magnification is increased, both by the use of auxiliary lenses and higher magnification eyepieces, there is a divergence of the point on the subject where each optical path is focused and resolution appears to degrade. This is what limits the effective magnification range of this design to approximately 125x.

Stereo microscope CMO versus greenough optical design.

The images below were captured from the left and right eyetubes on a Greenough stereo microscope. As you can see, the crossline in the left image is offset to the left, and the crossline in the right image is offset to the right. Everything is exactly the same for these two images except for the moving camera from the left to the right eyetube. Specifically, this is exactly what a Greenough system should look like, because this is how the microscope system generates a three dimensional type of image.
