Description
The Fourier Optical Measurement System (FOMS) is a tool for assessing the Quantum Efficiency of solar cells. Its unique design allows for a full determination of the EQE curve in mere seconds. This makes FOMS 2 to 3 orders of magnitude faster than current EQE systems. In addition to EQE of solar cells, FOMS can perform reflectance and transmittance measurements of (solar cell) materials. This makes FOMS a very versatile instrument for PV R&D, allowing you to quickly and reliably perform experiments under the same, controlled conditions.
