IMAGING-PAM

The IMAGING-PAM technology brings the power of the proven Pulse-Amplitude Modulation (PAM) principle into the realm of high-resolution, image-based chlorophyll fluorescence analysis. This approach delivers detailed, spatially precise insights into photosynthetic performance - non-invasive, highly sensitive, and ideal for capturing the dynamic responses of plants under real-world conditions. From fundamental plant physiology to advanced research on photosynthetic efficiency, stress resilience, and environmental toxicology, IMAGING-PAM systems offer researchers an exceptional window into the function and health of photosynthetic organisms.

The IMAGING-PAM M-series stands out through its modular, forward-looking design. All systems operate with the same Multi Control Unit IMAG-CG, and the camera can be used interchangeably across versions. This versatility enables seamless adaptation to different experimental requirements, applications, and magnifications, making the IMAGING-PAM M-Series both cost-effective and exceptionally flexible. In addition, all systems can be fully programmed for automated measurement routines and operated remotely via the ImagingWinGigE software, supporting long-term experiments and high-throughput workflows with minimal manual intervention.

Excitation Wavelengths and Filter Sets
The MAXI, MINI, and MICROSCOPY versions are available with blue, red-orange, and GFP-specific LEDs and dedicated filter sets. Blue excitation is standard for higher plants and algae, red-orange is recommended for cyanobacteria.

Actinic Light Intensity
High-performance power LEDs deliver up to 5,000 µmol m⁻² s⁻¹ (depending on version and configuration) for precise simulation of high-light stress and dynamic illumination conditions.

Ambient Light Compatibility
The systems support measurements under continuous ambient light. IMAGING-PAM devices communicate directly with the Universal Light Meter ULM-500 to automatically integrate real-time ambient PAR values into the report file.

Suspensions and Combined Techniques
Additional filter plates improve image quality for liquid suspension measurements through reflective surfaces. Dedicated adapters enable combined PSII imaging and gas-exchange analysis under controlled environmental conditions.

MAXI Version
The largest imaging area in the M-Series — ideal for whole leaves, multiple samples, fruits, and corals. The MAXI LED array provides homogeneous illumination over the full measuring area. Available with the Fruit Adapter IMAG-MAX/HF for curved surfaces. Can be combined with the GFS-3000 via the large Gas-Exchange Chamber 3010-GWK1 for simultaneous fluorescence imaging and gas exchange over 10 × 13 cm².  Go to MAXI Version

MINI Version
Compact and field-portable with a leaf clip holder for single-leaf measurements. The MINI version connects to the GFS-3000 Standard Measuring Head via the snap-on Adapter IMAG-MIN/GFS for combined fluorescence imaging and gas exchange. Ideal for researchers who need imaging in the field or want to add spatial resolution to their gas exchange experiments.  Go to MINI Version

MICROSCOPY Version
Integrates with a Zeiss Axioscope 5 microscope for cellular-level chlorophyll fluorescence imaging. Designed for single-cell analysis, tissue sections, and microalgae. The highest spatial resolution in the M-Series.  Go to MICROSCOPY Version

MOBILE Version
A lightweight, standalone imaging head for field measurements on flat surfaces. Designed for rapid screening in the field or greenhouse without a full laboratory setup.  Go to MOBILE Version

3D Version
Captures chlorophyll fluorescence images on non-flat, three-dimensional plant surfaces. Extends the imaging capability beyond planar samples to whole shoots, rosettes, and complex canopy structures.  Go to 3D Version

For automated, multi-sample screening applications, the HEXAGON-IMAGING-PAM provides a large-area imaging platform with a 20 × 24 cm measuring area. It is designed for plant phenotyping and high-throughput workflows.
