An Introduction to Computational Clearing

Many software packages include background subtraction algorithms to enhance the contrast of features in the image by reducing background noise. The most common methods used to remove background noise…
Extended Depth of Focus (EDOF) images

How To Create EDOF (Extended Depth of Focus) Images

Watch this video to see how you can rapidly record sharp optical microscope images of samples with a large height variation. This is done with the optional Extended Depth of Focus (EDOF) function of…

Real Time Images of 3D Specimens with Sharp Contrast Free of Haze

THUNDER Imagers deliver in real time images of 3D specimens with sharp contrast, free of the haze or out-of-focus blur typical of widefield systems. They can even image clearly places deep inside a…

Forensics microscopy

Every Clue Counts – Forensics Inconceivable Without Microscopy

There is no crime without clues. They may be obvious, like a cartridge case at the scene of the crime or clear signs of crowbar damage on a door. But sometimes, clues are microscopically small.…
QTM B, 1963, the first commercial automated image analysis system for microscope images, based on a TV camera and developed by Metals Research in Cambridge, England.

50 Years of Image Analysis

Modern image analysis systems perform highly sophisticated image processing functions on images from an automated microscope and digital camera. 50 years ago, the first image analysis system was…
