Ultra-High Sensitivity, Progressive Scan, Digital Output Video Camera
MC285SPD-L0B0 - TI Japan introduces the MC285SPD-L0B0, a 1M-pixel, charge multiplication CCD video camera with 30 fps video output. This latest IMPACTRON™ camera combines high resolution and real-time imaging with extraordinarily low noise and high quantum efficiency (peak QE >60%). TI's IMPACTRON™ charge multiplication technology is completely immune to common problems of conventional image intensifier technologies such as image burn-in or residual imaging. Furthermore, the charge multiplication gain is variable, allowing for adjustments to suit a wide range of light conditions. The MC285SPD-L0B0 is an astounding camera that was created for use in applications for which real-time, high-resolution, and high sensitivity are required. The CCD in the camera is cooled to approximately -20 degrees Celsius. Additionally, this camera features RS-232 controllability. Functions such as charge multiplication gain, exposure, 2 x 2 or 4 x 4 column/row binning, and image averaging can all be modified through a standard serial port interface common to almost all PCs and laptops.
▶ On-Chip Charge Multiplication
The charge is multiplied, stage by stage, in a special 400 stage charge multiplication register.
▶ Lowest Power EMCCDs (20 Volt Max)
Unlike traditional image intensifier technology, a 20 volt clock signal applied to CMG register can
result in a gain of about 2000 x.
▶ Low Noise due to charge multiplication before output amplifier
A charge conversion amplifier has its own inherent noise. Since IMPACTRON™ achieves the
desired gain through charge multiplication before entering the conversion amplifier, the noise of
amplifier becomes negligible overall as CMG gain increases.
▶ Peltier Cooling for even better noise performance
By cooling the CCD, dark current is significantly reduced.
▶ No burn-in or residual imaging
Impact Ionization Theory
The potential difference at P4 determines the extent of Impact Ionization (Charge Multiplication)（In charge multiplication, electrons passing through a high energy field collide, generating additional electrons）
Lens is not included.
