CIMPS

Zahner's CIMPS is an LED-based system which is designed for photoelectrochemical or photovoltaic applications. Using an active light feedback loop the CIMPS system ensures a controlled light intensity during the measurements. A wide variety of monochromatic LEDs from UV to near IR is available for the CIMPS-system. Extensions for light emission, absorption, transmission or light transient measurements increase versatility of the CIMPS-system.

Light sources

The CIMPS system uses monochromatic LEDs as light sources. The light sources are "plug and play", they are automatically detected by the software. Each LED delivered with the CIMPS system is individually calibrated to provide accurate illumination during the experiments.

Monochromatic LEDs

Extensions

The CIMPS system can be extended for different dedicated experiments. Extension options are listed below.

Accessories

Photoelectrochemical measurements are carried out in a controlled light environment. For this purpose, Zahner has designed a light exclusion box (LEB). This LEB can accommodate the complete optical bench with light source and sample. The LEB also serves as a Faraday cage and diminishes artefacts at low current measurements.
