Stereo

Stereo Microscopes

Stereomicroscopy is an indinspensable tool for applications where large working distance and hand-eye coordination are required. This type of Optical Microscope produces a 3D true-to-life images with depth perception. Hence is worthily considered to be an ideal instrument for examining large biological samples or rough material surfaces and manipulation tasks (such as dissection, microsurgery etc.) where a 3 dimensional view in demanded to study the details.

Concept

A Stereo (often referred to as Low Power or Dissecting Microscope) is a type of Optical Microscope producing a three-dimensional view of the specimen. In order to accomplish this task it is equipped with separate objective lens and eyepiece for each eye. This design allows the right and left eyes to observe the same object at slightly different angles. The principle of 3D image forming technique is very similar to what happens with human eyes - 2 independent optical paths in the microscope provide 2 different viewing angles of the same sample yielding a three-dimensional image.
This type of Optical Microscope is designed for low magnification applications typically up to around 100x (total magnification power in some high-end instruments can achieve up to 300x) and commonly uses reflected illumination technique ensuring efficient examination of items too thick or opaque for a Compound Light Microscope. It features great working distance and depth of field. The large working distance at low magnification is utterly helpful in examining large solid objects (such as fracture surfaces) with complex surface topography where a three-dimensional observation is needed for analyzing the details. The trick with most optical inspection tasks is only to use just enough magnification as is required to view the specific detail you want. This retains depth of focus and large field of view.

Illumination

Illumination plays a great role in any Optical Microscope and Stereomicroscope is not an exception. Properly selected illumination is a key to bring all the work to light. To match the right application conditions different illumination methods are available to apply - transmitted light; brigthfield/darkfield illumination; fluorescence enabling to examine an extensive range of specimens starting with rough opaque items and ending with transperent samples either colorless or with high contrast and sufficient color information.
As small preparations require intense illumination Stereomicroscopes are equipped with a fibre-optic light source, but using a high-power LEDs are becoming a more common provision, because they are much more efficient than halogens and are capable of delivering a spectrum of colors light especially useful for fluorophore analysis in Biology.
