Customizable Mapping System for R&D Needs

Flexible Mapping Tool for R&D

The HR-SPSmap product with a variable energy excitation source is built on the same robust foundation as the fixed-excitation HR-SPSmap system. This compact, benchtop, contactless electrical characterization tool is designed for offline production control and research and development applications. It provides precise surface photovoltage (SPV) measurements across a wide injection range, supporting both steady-state and short-pulse excitation. Additionally, it offers continuous wavelength sweeps for true spectroscopy measurements, enabling reliable characterization of any photoactive sample.

Versatile and Automated Adaptability

The HR-SPSmap system is engineered for flexibility and efficiency. Automated sample recognition and parameter configuration allow seamless adaptation to a broad range of samples, including epitaxial layers and wafers processed at various stages, from raw material to fully finished devices.

Whether for R&D innovation or stringent production monitoring, the HR-SPSmap with variable energy excitation delivers unmatched precision and versatility, setting a new standard in electrical characterization solutions.
