What is Dark Field Microscopy Used for?

Dark field is a lighting technique of oblique illumination used in microscope observation. With dark field condenser and special objectives, it can achieve a bright sample image with a black background. When the bright field illumination cannot provide sufficient contrast for observation, dark field illumination can be considered. Let’s have a detailed look at the principle, advantages and disadvantages, component of dark field and what is dark field microscopy used for.

Dissecting Microscope – Definition, Principle, Parts, Uses

The dissecting microscope, also known as the stereo microscope, provides you highly three-dimensional upright images through a dual-path optical system to show the depth and details of samples. The dissecting microscopes are widely used in dissection of small animals and tissue samples in biological laboratory experiments and teaching, as well as in industrial inspections to check circuit boards and welding. Let’s delve deeper into the dissecting microscope and get some suggestions for choosing one.
