This versatile high performance digital 14 bit CCD camera system is specifically designed for low light applications in the range of visible light up to 1100 nm. The pco.1400 has an extraordinary quantum efficiency (QE) of up to 65 % @ 500 nm (12 % @ 880 nm). In addition a proprietary offset control algorithm has been added which provides very high offset stability. Some of the pco.1400‘s unique features are its increased sensitivity in the NIR range of the spectrum and the „no glow“ functionality. Binning can be selected to accomodate the user‘s application. Camera features excellent resolution (1392 x 1040 pixel), high dynamic range, exposure times from 1 µs to 60 s, excellent low noise of 6 e- rms @ 12.288 MHz, high framing rate 13.5 fps @ 25 MHz and standard interface IEEE 1394a („Firewire“).

QE curves - pco.1400

Quantum efficiency curves of the pco.1400 CCD image sensor in two different operating modes (measured by pco).

Electroluminescence image of a solar cell within a panel

Electroluminescence image of a solar cell within a panel panel operated in forward current mode. The dark areas indicate defects in the cells crystal, which would not contribute to the generation of photovoltaic current (the monochrome image was false color coded for better evaluation).

Electroluminescence image of a solar panel

Electroluminescence image (false color coded) of a solar panel with poly-crystalline solar cells. Darker areas indicate areas or crystal layers, which do not contribute to the solar current generation.
