PHOIBOS 225 1D-DLD

High Peformance Hemipsherical Energy Analyzer with 1D-DLD detector for UPS, XPS, ISS and LEISS.

The PHOIBOS 225 hemispherical energy analyzer is a powerful tool for modern photoelectron spectroscopy. This analyzer can be operated in all relevant analysis modes, such as 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. It can easily be upgraded with all available SPECS detection systems.

The integrated 1D-DLD detector is the best performing detection system available. The direct detection of electron signals yield quantitative counts per second (cps). The powerful electronics can aquire ultrafast snapshot measurements of the energy spectrum with up to 1200 energy 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 section is equipped with 8 customizable entrance and 3 exit slits for UPS and XPS. The analyzer comes with a highly stable power supply, the HSA 3500 plus, for best performance in a wide kinetic energy range up to 3500 eV kinetic energy.

XPS, Chemical Mapping

X-ray photoelectron spectroscopy (XPS) is a widely used method for chemical analysis. By surface imaging or mapping a chemical map can be recorded

AES, SAM, SEM

Auger electron spectroscopy/microscopy detects the energy distribution of secondary electrons returning from a surface locally for chemical analysis.

ARPES

Angle-Resolved Photoelectron Spectroscopy detects the energy and angle distribution of photoelectrons to determine the electronic structure of solids.
