Working Distance – Definition, Measurement, Types, Importance

What is Working Distance? In optics and microscopy, working distance—a fundamental idea—is the empty space between the object of view and the front surface of the lens or lenses in a microscope. Measuring in millimetres (mm), this distance greatly influences our perspective of objects under microscopes. Consider yourself examining little items under a microscope. Between … Read more

Pocket Microscope – Definition, Parts, Principle, Uses, Types

What is a Pocket Microscope? A pocket microscope is a compact optical instrument that professionals and hobbyists alike can utilise. These microscopes– which are specifically engineered to be portable, feature a diminutive form factor that makes them truly pocket-sized, though certain models are marginally larger. Like most microscopes, they incorporate a small platform for specimen … Read more

Polarizing Microscopes – Principle, Definition, Parts, Applications

What is Polarizing Microscope? Polarizing microscopes, also called petrographic microscopes, are specialized optical instruments designed for the examination of specimens that display birefringence—materials that divide light into two rays that propagate at different velocities. This unique property allows scientists to study the optical properties of anisotropic substances, which have properties that depend on direction. But … Read more

Inverted Microscope- Definition, Principle, Parts, Labeled Diagram, Uses, Worksheet

Inverted Fluorescent Microscope

An inverted microscope is a special type of microscope. It doesn’t resemble other regular microscopes, as the light source and condenser point upward to shine directly downwards onto the specimen stage. The objective lenses, along with the turret, face up from below the stage. In other regular upright microscopes, the stages have objectives facing up … Read more

Digital Microscope – Principle, Parts, Application, Advantages

Parts of a Digital Microscope

A digital microscope is a brilliant optical innovation, fundamentally distinguished from a normal microscope simply because it does not employ any eyepiece. The digital microscope uses a digital camera as its image detector and projects the images onto a computer monitor or screen. The entire process eliminates human interaction with the optical system; all the … Read more

Darkfield Microscope – Definition, Principle, Uses, Diagram

Dark-Field Microscope

The darkfield microscope dates back to the early 19th century with some of the developments in optical microscopy. It was then that scientists started conducting experiments on different illumination techniques in a quest to maximize contrast for observing transparent and fragile specimens. Toward the late 1800s, the darkfield technique became quite popular, especially when live … Read more
