The monochrome e2v ELiiXA 4S camera is an 18 kHz, 4096 pixel camera, with extremely high sensitivity, ideally suited for low light use, an application currently only addressed by TDI cameras. The ELiiXA 4S camera is targeted at requirements traditionally addressed by dual-line and TDI cameras. When compared to TDI, the ELiiXA 4S offers more flexibility in lighting requirements and positioning, plus an increased MTF immunity in sharp variations in web speed. The ELiiXA 4S monochrome camera is extremely flexible (Camera Link interface, various trigger modes, multiple output modes and bi-directional scanning) and easy to integrate within a system, thanks to their automated balance settings (sensor tap balance, flat field correction, line balance). The EliiXA 4S is ideally suited to low light surface inspection, UV or NIR wavelength scanning (archiving of sensitive documents, biotech plates reading) and specific web inspection.
