Our recent result demonstrates an ultra-fast multi-channel coincidence counting unit with full channel-number resolution, which meets the requirements of cutting-edge photonic experiments.
Digital pulsebox
Our work on the arbitrary digital pulse sequence generator using delay-loop timing of a microcontroller was published in Rev. Sci. Inst. 89, 045103 (2018), https://doi.org/10.1063/1.5019685, arXiv. Any uC can be used to get timing accuracy at the level of two or
Home-made four channel voltmeter
In brief: We often measure voltage in QOLO, that’s why we created a custom four-channel ADC box. There are possible three levels of use – PyQt GUI application, python module in your scripts and commanding arduino anyway you want. Details
Monitoring and real-time plotting of the temperature and relative humidity in QOLO
The facade of our building is covered by dark stone and our lab is equipped by a huge south-east facing window. The air condition in the lab consists of a small wall-mounted AC unit and mechanical ventilation input and output
30 ms optical shutter using RC servo
In QOLO we use shutters mainly for switching between different input signals, such as probe laser and single photons, and for closing individual paths of complex interferometric setups. Typically, there are two methods how to achieve this goal based on
3D design of optomechanical and electronic systems
With Google SketchUp it is easy to make 3D models and even quite complicated 3D scenes. Libraries of optomechanical components can speed up the process of an optomechanical setup documentation, presentation or prototyping. Newport offers 170 product models via Google’s
Interference filters at off-normal angles of incidence
Majority of interference filters are designed to be used at normal angle of incidence (AOI). The primary effect of an increase in the incident angle on an interference coating is a shift in spectral performance toward shorter wavelengths. In other
