Photon etc. offers complex material analysis (GaAs, SiC, CdTe, CIS, CIGS) using hyperspectral imaging of diffuse reflectance, photoluminescence, electroluminescence and Raman signals. Our technology is based on high throughput global imaging filters, faster and more efficient than spectrograph based hyperspectral systems. Imaging from 400 to 1000 nm with a bandwidth of 2 nm, Photon etc’s IMATM is capable of measuring opto-electrical properties such as Voltage Open Circuit and External Quantum Efficiency, and allows precise detection and characterization of defects in materials. Researchers and QC analysts will greatly benefit from this new innovation.
With Photon etc’s PLM-HI, the detection is made one wavelength at a time, but simultaneously on the whole sample. For each point of the field, the output is a monochromatic beam at wavelengths determined from the central pixel wavelength and the horizontal distance from that pixel. This creates a gradient of wavelengths across the field-of-view. By taking a series of images, PHySpec, our proprietary software, produces a hyperspectral cube with purely monochromatic images, allowing spectral analysis in each and every pixel of a full resolution image. Different excitation sources (UV-VIS-NIR) can be included: supercontinuum, Xenon lamp, Tunable Laser Source, etc.
PLM-HI is controlled by PHySpec, a user friendly software also controlling the XYZ translation table for sample positioning. It displays two modes of operation: spectral mode and video mode.
The acquisition is done when the filtered light coming from the sample is treated by PHySpec. This mode gives access to a set of monochromatic images from the whole sample, allowing identification of its different constituents.
Video ModeThe signal reaches the detector without wavelength selection, allowing a direct visualisation of the sample and a continuous monitoring of the photoluminescence distribution and its fast variations.
