This is amazing! Within one year 6600 visitors visited our page. Assuming that 85% are bots, the number of human visitors still sums up to around 1000 people that are interested in what we are doing. 🙂 In order to keep you up to date, we are still struggling with our Coherent® LIBRA systems. 🙁
DCU 600 – Error: 026
Isn’t it annoying, you are running a turbo molecular pump worth thousand of dollars and it fails to operate!? In our lab we use several TMH/TMU 1600 C pumps, two of them controlled by the (more or less) modern DC 600 controller unit. Exactly this unit showed us an error message, namely Error 026. Here is how we fixed it. (more…)

The PI Mercury™ C-863.10 and PI Mercury™ C-863.11
The PI Mercury™ C-863 is a DC-motor controller which exists in two versions, i.e., the C-863.10 controller and the C-863.11 controller. Both differ in their firmware and their hardware. That makes it difficult to control them using the same software. Here you’ll find some information on how to deal with the new General Command Set of the Mercury™ C-863.11 controller. (more…)

MHB-382SD Datalogger
We use the MHB-382SD Datalogger to monitor temperature, humidity and pressure in our laboratories. The logger saves the recorded data into a XLS-file. The following zip file contains an executable (Windows 64bit only) which was programmed in LabView 2012. It can be used to display data from the logging device and copy selected data to your computers clipboard:

If you want to know more about the MHB-382SD, please refer to the following manual.
If there is any problem with the program, please keep us informed by using the comment box below.
How to align a translation stage
Femtosecond spectroscopy uses an ultrashort laser pulse to start a photo-chemical reaction at a well defined moment in time. A second ultrashort laser pulse can be used to visualize the ongoing photo-chemical reaction [1]. To achieve a precise timing between two laser pulses, a laser beam is usually split into two parts. One part of the beam is directed towards the experiment, the second part passes a translation stage before recombination of both beams occurs. By precisely moving the translation stage by a certain distance, the pathway is increased and laser pulses will arrive with a time delay Δt=Δx/c, where c is the speed of light.
