What Can I See Under the Microscope?

This image shows the size of items that can be seen with the human eye, a light microscope, and an electron microscope.

Microscope Resolving Power

Keep in mind that more magnification is only better if the resolution is also good. There are several great images here that show microscope magnification resolution.

Protozoan Parasite under the Microscope

OE (Ophryocystis Elektroscirrha) is a protozoan parasite that infects butterflies in the Danaus species group, those that host on milkweed. This photo of some Monarch butterfly abdominal scales was taken by Rob Wood with a Canon 80D DSLR through a Richter Optica HS-3 Biological microscope, at 400X. The large objects are scales, while the football-shaped objects are OE spores. Each spore contains 8 protozoa.

Woody Stem Under the Microscope

Below is a woody stem cross section captured under the Richter Optica UX1 cordless student microscope captured at 400x magnification. This image was captured using the DCM5 microscope camera (5.2 megapixels).

The woody stem produces wood as its structural tissue - typically either a tree, shrub or liana.

pco Cameras

Microscope World is proud to offer pco scientific cameras. The pco cameras are known for their low readout noise, high frame rates and exposure times that range from nanoseconds to hours. UV and NIR detection and high dynamic range are just some of the pco cameras' unique core competences.

Microscope World offers the pco.panda 4.2 camera.
pco.panda 4.2 Camera


The pco.panda 4.2 camera combines revolutionary sCMOS technology in a compact design. High quantum efficiency (up to 80%) and low readout noise make this camera suitable for countless applications. The USB 3.1 interface enables ultra-speed data transfer and direct power via the USB cable, making external power supplies redundant. Frame rate = 40 fps @ full resolution 2048 x 2048, 80 fps @ 2048 x1024.

Fluorescence Microscopy

Fluorescence microscopy is a tool used in biology, material science, and biomedical sciences. The fluorescence microscope can reveal the presence of a single molecule. The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths, and then to separate the much weaker emitted fluorescence from the excitation light.

The fluorescence microscopy images shown below were captured using the Fein Optic RB30-GFP fluorescence microscope and the Lumenera Infinity 3S-1UR microscope camera.
