- What is an Optical Microscope?
Optical microscopes come in numerous shapes & sizes and are widely used in schools, the research & manufacturing industries, hospitals, etc. However, did you know that there are actually 2 main classes of optical microscopes, each having different advantages & limitations? […]
- Reflective Versus Transmission Light
Reflection is the process by which electromagnetic radiation is returned either at the boundary between two media (surface reflection) or at the interior of a medium (volume reflection), whereas […]
- Digital or Traditional Microscopy?
The most traditional form of microscopy is optical microscopy, also known as light microscopy where it use visible light to view a sample through the magnification of a lens system […]
In microscopy context, magnification is refers as the amount or degree of visual enlargement of an observed object. It is measured by multiples, such as 2x, 4x and 10x, indicating that the object is enlarged to twice as big, four times as big or 10 times as big, respectively […]
- The Working Principles of Microscope
A general optical microscope mainly consists of an objective lens, ocular lens, lens tube, stage, and reflector. An object placed on the specimen stage will be magnified through the objective lens. When the target is focused, a magnified image can be observed through the eyepiece […].
Resolution is defined as the ability to distinguish two objects from each other. In other words, this is the minimum distance at which two distinct points of a specimen can still be seen – either by the observer or the microscope camera – as separate entities […]
- Diffraction Limit of Light
Optical Microscopy, or light microscopy uses visible light to transmit through, refracted around, or reflected from a specimen. The power to magnify the image of the specimen when viewing through a microscope depends on how much the lenses bend the light waves […]
- Numerical Aperture
Numerical aperture (NA) or also known as Object-side aperture is a value that measure the angular acceptance for incoming light It is defined based on geometrical consideration and is thus, a theoretical parameter that is calculated from the optical design. […]
