Light Microscope. 6 What are the different types of microscopes used in laboratories? 6014 , CY. Key Differences Between Light and Electron Microscope One of the characteristic difference is that a light microscope uses a light source, whereas an electron microscope uses a beam of an electron. A light microscope provides a magnification of up to 1500x, but 1000x is more common. Their ability to function is because they have been constructed with special components that enable them to achieve high magnification levels. This website uses cookies to improve your experience while you navigate through the website. The microscope has the power to show details of an object more clearly. SEM and TEM are analytical instruments that we use in electron microscopy to get an image of a tiny object using a beam of electrons. A light microscope is a microscopy instrument that uses light to image objects. There are even some microscope designs that combine both the slides and the cells into one single unit. In addition, it requires high technical skills to use and is therefore limited to specialized use such as research. In an electron microscope, the resolution is about 0.0001m, i.e. It requires no special skills to use. Wavelength is 100,000 times shorter than visible light, hence much more clarity. Advantage: Light microscopes have high resolution. High voltage electric current is required (around 50,000 volts and above). There are two main types of microscope: light microscopes are used to study living cells and for regular use when relatively low magnification and resolution is enough electron microscopes.

The resolution (the level of image detailing) is the main difference between these two microscopes. Most compound light microscopes produce flat 2D images because high-magnification microscope lenses have inherently shallow depth of field rendering most of the image out of focus. var hs = document.createElement('script'); hs.type = 'text/javascript'; hs.async = true; 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. Illuminating light pass through the air. Light microscopes use a condenser above the light source in order to focus and direct the light up through the specimen (in a small beam of light) and into the eyepieces.
