Countdown to a Revolution in Microscopy – Day 5
The foundational design of the compound microscope has, in many ways, remained locked in place for the 450 years of it’s existence. Combining an objective, eyepiece, and illuminator to provide a magnified view of a specimen has drastically improved. The illumination, staging, detection, optical design, and contrast methods have all evolved by leaps and bounds…

Running HASP Licenses on Virtual machines
One of the downsides to using OSX for my primary operating system is that most of the major imaging programs are windows-only. To compound the trouble, many of these programs, like NIS Elements, use the “HASP” license manager to communicate with a security key in order to fight piracy. So, you have to have this…

Arduino Mega 2560 Comparator
So I needed to set up an Arduino Mega as a signal processor. I had a sawtooth signal coming from a device, and I wanted to convert that signal to a 0/5V TTL signal. Now, with something like a sine or sawtooth wave, the question becomes, “At what point do I want to consider this…

Identifying Astigmatism in your microscope
After all of the engineering and testing which goes into a microscope, you’d imagine that any manufactured scope would have perfect alignment of the optics. Believe it or not, in many cases things can be off! So how can you tell this? A simple test is to view a bead slide, or a grid slide,…

MetaMorph, Elements, Micro-Manager intermittent Crashes may be due to power options
Does your system crash when taking a timelapse, or just every so often, but isn’t linked to a specific set of actions you take? Or, does your camera run slowly for no apparent reason, only sometimes? Here’s a basic set of checks to do before targeting the software drivers or hardware. Windows power options So…

Is there anything cooler than drilling gigantic holes in the ground? Yes – Blowing stuff up afterwards!!!
I’m sure this study involved no fun whatsoever 🙂 http://www.nature.com/nature/journal/v518/n7537/full/nature14146.html -Austin

Wide-field, high-resolution Fourier ptychographic microscopy end runs conventional limits to resolution
Dane Maxfield from Technical Instruments send me this interesting article from Nature. It’s great to see the power of image processing be used in such a way, and my guess is that this type of image+software+hardware combination will yield excellent new technologies in the future. -Austin
