FLI -MicroLine CCD Camera AIMO back illuminated midband (no shutter)
The ML4720 uses a back-illuminated frame transfer sensorfrom e2v technologies. Half of the sensor is covered with a metal mask; half is exposed to light.
The exposed side of the sensor is centered in the camera aperture. The image is moved from the exposed side to the masked side in about 10 milliseconds, then read out from the masked side while a new exposure is integrating on the exposed side. (Therefore, frameto-frame timing depends in great part on the digitization speed.)
The default configuration for the camera is two channel readout with software-selectable digitization speeds of 500 kHz and 4 MHz per channel. (Single channel readout is available on request, as are different digitization speeds.)
The midband and broadband versions of the sensor are operated in MPP mode (low dark current). The UV version of the sensor is non-MPP
