PHOCUSCAN: High-Precision Photocurrent Mapping System

The PHOCUSCAN is a compact, high-performance scanning photocurrent microscope (SPCM) purpose-built for accurate photocurrent mapping and device analysis. With sub-100 nm laser scanning resolution and dual-mode operation, it enables both brightfield imaging and real-time electrical measurements in a single platform.

Designed for versatility, PHOCUSCAN supports the full VIS–NIR range (400–1000 nm) using a super-apochromatic optical system and offers seamless compatibility with Keithley 2400/2600 series source-meters. It includes ultra-smooth multi-axis micro-positioners, an interchangeable chopper module, and a vacuum chuck stage for stable, precise sample handling.
