PHOIBOS 150 WAL 2D-DLD
Wide Angle Analyzer for ARXPS with 150 mm Mean Radius with 2D DLD Detector and ±30° Accpetance Angle.
The PHOIBOS 150 hemispherical energy analyzer is a powerful tool for modern photoelectron spectroscopy. This analyzer can be operated in all relevant analysis modes, such as XPS, ARPES, as well as AES, ISS and LEISS. Its design and the modular supplementary hardware makes this analyzer the most versatile PES analyzer in the market. It can easily be upgraded with all available SPECS detection systems.
Its special wide angle lens covers the range of ±30° to efficiently cover the relevant wide angular range for angular resolved XPS. That allows to measure the depth profile of a sample at up to 3500 eV kinetic energy without sample destruction. Also ARPES (UV Range) with an identical accpetance angle is possible.
The integrated 2D-DLD detector is an ultrafast 2D single event detection system. The direct detection of electron signals yield quantitative counts per second (cps) in the energy and angular/second dimension. The powerful electronics can aquire ultrafast snapshot measurements of the energy spectrum with up to 1000 energy (anguklar channels as well as continous sweeping energy spectra. Its low dark count rate and high linearity make this detector outstanding for XPS analyis.
The energy analyzer sectionis equipped with 8 customizable entrance and 3 exit slits. The analyzer comes with a highly stable power supply, the HSA 3500 plus, for best performance in a wide kinetic energy range.
