95% QE SCMOS vs. EMCCD

In 2011, I reviewed the Andor Neo, one of the first scmos cameras commercially available. I ended my report with this statement, “…there is much life left in the good old frame transfer sensor…until someone cooks up a back thinned scmos…” Recently, back thinned scmos camera have come to market, and Kurt Thorne at the […]

Microscope Objective Zemax Files

While I haven’t had a chance to test these for accuracy, I was excited to find them while looking for some tube lens specs! You can find the file set here. These designs include some of the common infinity corrected objectives, as well as tube lenses, from every major microscope manufacturer.

Optical Design comes to the iPad!

Over the past 5 years, almost every project I’ve worked on has required some level of optic design. In many cases, simple designs suffice. For example, projecting an LED can be accomplished at a basic level with an aspheric condenser. But when designs require flat fields, especially corrective elements, or apochromatic performance, it’s time to leverage commercial […]

A serial monitor that works in Win7x64!

David Biggs at KB Imaging LLC put me onto this serial monitoring software, called SUDT Accessport . I’ve used it a bit for some work on the triggerscope, and it works very well! You can watch data transmitted between USB emulated serial ports, under RS-232, and it will output the communication in either ASCII or HEX. […]

How to use external triggers on scientific and industrial cameras

Controlling a camera from an external trigger can be very useful. External triggering provides greater timing accuracy, direct control over exposure duration, and remote operation from TTL devices. This is a prime reason I made the Triggerscope controller, so I though it would be useful to explain how this works and what you can do […]
