Introduction and history of a digital microscopes A digital microscope is a modern microscope that lacks an eyepiece, an immense difference from the traditional optical microscope. They have a digital camera which is the detector and the image output device. The display of the image is done on a computer screen or monitor, defining the … Read more Digital Microscope
Introduction and History of the Confocal Microscope The concept of confocal microscopy was initially developed by Marvin Minsky in the 1950s, at Harvard University with an aim of viewing the neural network without staining the tissues but it did not bear fruit due to lack of enough light source and a computerized system to store … Read more Confocal Microscope

Lawrence Smith, this microscope just like it sounds is a light microscope which has its components placed in an inverted order, this means, light source and condenser lens are placed above the specimen stage, … Read more Inverted Microscope
The first Scanning Electron Microscope was initially made by Mafred von Ardenne in 1937 with an aim to surpass the transmission electron Microscope. He used high-resolution power to scan a small raster using a beam of electrons that were focused on the raster. He also aimed at reducing the problems of chromatic aberrations images produced … Read more Scanning Electron Microscope (SEM)
