The newest addition to the Andor sCMOS camera portfolio, the Zyla 4.2 utilizes a high Quantum Efficiency (QE), low noise sensor variant, yielding frame rates up to 100 fps (faster from region of interest). The Zyla 4.2 is ideal for applications that benefit from optimal sensitivity and speed, such as calcium imaging, light sheet microscopy and super-resolution microscopy.
Zyla 4.2 delivers > 72% QE and down to 0.9 e- read noise, making it the most sensitive sCMOS camera available. The darkcurrent at 0°C is extremely competitive, at only 0.14 e-/pixel/sec benefiting from Andor's Dark Noise Suppression (DNS) Technology. Under moderate to fast frame rate operation, the Zyla 4.2 excels.
The ‘4T’ (4-transistor) design of the sensor pixel permits more photons to enter, driving Quantum Efficiency up to 72 % (@ 580nm). The 4T design also means that it is fundamentally a Rolling Shutter sensor. However, a feature called ‘Global Clear’ has been implemented, which allows for a simulated Global Exposure mode, which requires TTL communication between the camera and a pulsed light source, emulating the Global shutter exposure condition, albeit with less efficiency.
