Microscopes are complex instruments that use multiple components to produce enlarged pictures of the specimens. They use different types of lenses to magnify the image and view them on the eyepiece or monitor. Microscopes of all types, including optical and electron, use objectives and condenser lenses to give you the observation. However, light and simple microscopes do not use the same lenses. So, what do condenser and objective lenses exactly … [Read more...]

Microscopes are inevitably the most important instruments in scientific research. They help us understand the structure and composition of various microbes around us. Light and stereo microscopes are widely used in schools and industries. They look quite alike and use a similar mechanism of action. Sometimes, students and researchers have to draw these microscopes for studies and presentations. So, if you are looking for detailed instructions on … [Read more...]

I always find microscopes an incredible invention; who thought you could see microorganisms through a glass lens? Thanks to researchers and scientists, we can now magnify objects thousands and millions of times using an electron microscope. While electron microscopes are known for high magnification, optical microscopes are also quite useful in schools and research labs. An optical microscope with a 100x objective lens and a 25x eyepiece gives … [Read more...]

Microscopes are critical to observing the in-depth structure of microscopic organisms around us. While optical and electron microscopes both contribute to the visibility of an organism, most students and researchers use light microscopes. However, the light microscope has its own limitations. For example, it cannot observe less than 200 nm. If you wonder why, you’re at the right place. This article focuses on why is a specimen less than 200 nm … [Read more...]

Microscopes are critical to examining and understanding objects and specimens invisible to the naked eye. There are some of the best stereo microscopes that help you study the samples using two types of lenses (objectives and eyepieces). At the same time, electron microscopes have a more complex assembly. However, microscopes in the past did not have multiple lenses. The earliest microscopes (single-lens microscopes) had only one lens; used in … [Read more...]
