Eagle V - 4MP ultimate sensitivity vacuum cooling CCD for long exposure imaging!
Raptor Photonics, a global leader in the design and manufacture of high performance digital cameras has launched the Eagle V, a “best in class” deep cooled vacuum based CCD using Raptor’s revolutionary vacuum technology PentaVacTM.
Photon-starved scientific applications, including areas of in-vivo imaging, fluorescence, adaptive optics and astronomy, push the detection capability of today’s sensor technology to the limit. Back-thinned CCD sensor arrays are the detector of choice for many ‘staring’ applications, which require the use of both long exposure times (ranging from tens of minutes to hours) and binning (on-chip charge summation) in order to acquire a detectable signal. The overall noise floor of the camera, dictates the low level detection limit of a specific imaging system, therefore minimizing both dark noise of the CCD sensor and noise associated with the readout circuitry are necessary to deliver the ultimate low photon detection limit.
The Eagle V uses a 4MP CCD42-40 Back Illuminated, AIMO sensor from e2v technologies. The sensor is 2048 x 2048 pixels with 13.5μm x 13.5μm pixels, with full well capacity of 100,000e- enabling optimum photon collection and a large field of view imaging combined with ultra-sharp image resolution. The Eagle V achieves a QE greater than 90% at 525nm and 50% at 380nm & 720nm.
PentaVac technology combined with multistage TECs and liquid allows active cooling to temperatures lower than Δ116°C, delivering extremely low dark current (0.0001 e/p/s) for exposure times of up to several hours.
The Eagle V runs at 16-bit digital output through a CameraLink data interface delivering low read out noises, 2.3 e- rms @ 75kHz pixel readout rate. The camera also operates @ 2MHz pixel readout rate, with 9.0 e- rms. Binning, up to 64 x 64 can be applied for ultra-weak signals.
