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

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

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
