Zahner CIMPS-QE/IPCE System

ZAHNER’s CIMPS-QE/IPCE system is a fully integrated and compact workstation for high-accuracy QE/IPCE measurements at the push of a button. Compared to competing products, setting up and running experiments with the CIMPS-QE/IPCE system is quick, easy, and does not require special knowledge or additional tools.

Key Features:

​

  • Easy-Mount Optical Bench
    All optical components are pre-aligned on a compact, easy-to-mount optical bench for fast setup and repeatable positioning.

  • Traceable Intensity Control
    An integrated PTB-traceable optical detector provides closed-loop feedback control of light intensity, ensuring absolute accuracy without reference cells or manual realignment.

  • Active Feedback Regulation
    Exclusive CIMPS feedback control maintains constant light intensity independent of LED temperature or aging.

  • Tunable LED Light Source (TLS03)
    A patented, LED-based tunable light source with linear monochromator delivers high intensity, narrow spectral bandwidth, and fast modulation—without filters or mechanical choppers.

  • No Warm-Up Time
    LED technology eliminates long warm-up periods typical of xenon-lamp systems while dramatically improving energy efficiency.

  • True Sine-Wave Modulation
    Real sine-wave light modulation without harmonic distortion, outperforming chopper-based systems.

  • Intelligent Wavelength Control
    Multi-LED architecture delivers higher power at selected wavelengths than xenon-lamp systems, with optional white background illumination for DSSC and tandem solar cell studies.

  • Wide Wavelength Coverage
    Standard range: 365–1020 nm
    Extended range: 295–1020 nm

  • Integrated Electrochemistry
    Full support for EIS, CV, polarization, and advanced electrochemical techniques.

  • Highly Expandable
    Optional modules support absorption/transmission, emission studies, fast intensity transients, and dynamic reflectance/transmittance.

  • Flexible Sample Handling
    PECC-1 and PECC-2 photo-electrochemical cells accommodate a wide range of sample types.

  • User-Friendly Software
    CIMPS-QE/IPCE software automates all components and reduces complex measurements to push-button operation.
