DetailHIS 13
The HIS 13 is a simple and easy to use UV light source with long time proven design.
The FOCUS HIS 13 is an easy to use and robust UV source. It provides an excellent He I to He II ratio and can be operated with many different gases. The source is designed for longest operation time with extreme stability and easy ignition.
The UV source fits literally every system on any free DN40CF flange, while the sample to flange distance is not critical. An optional polarizer is available to polarize the normally unpolarized light.
The monochromator delivers pure He I – w/o satellites or He II – lines for ghost peak free angle resolved photo electron spectoscopy (ARPES) or momentum microscopy. It is an option for the HIS 13 as well as the HIS 14 HD. For more details please refer to the dedicated section for HIS Mono.
A continously rotatable linear polariser allows for full use of symmetry selection rules in photoemission.
Attenuator for HIS 13/14 for VUV-sensitive samples. Even though most application in photo electron spectroscopy aim for maximum intensity there are opposite requirements when working on VUV-sensitive sample as for example organic materials. The Attenuator for HIS 13/14 allows for a variable reduction of photon flux by a factor 10 or 100.
