PHOIBOS 225 2D-DLD
Ultra High Resolution Hemispherical Energy Analyzer with 2D DLD detector for XPS, ARPES, ISS and LEISS with 225 mm mean radius and angular scanning.
The PHOIBOS 225 hemispherical energy analyzer is high resolution solution for photoelectron spectroscopy. This analyzer can be operated in all relevant analysis modes, such as ARPES, XPS, UPS, 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. Due to ist size and lens system, it shows highest values in energy resolution.
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. For highest energy resolution the entrance slit can be chosen down to 50 µm, providing achievable energy resolution better than 1 meV. The analyzer comes with a highly stable power supply, the HSA 3500 plus, for best performance in a wide kinetic energy range.
