Introducing the ZWO ASI432MM USB3.0 Monochrome CMOS Camera with Large 9 Micron Pixels
The ASI432MC is one of the latest monochrome CMOS cameras from ZWO which adopts the Sony IMX432 1.1" format 12bit ADC sensor. The 9um pixel size accommodates a well depth of a whopping 97ke with a total of 1.8Mpixels.
The NEW Solar imaging champion with global shutter! One could consider this as an upgrade to the ASI174MM, however the larger pixel size would make it quite a specialist camera suitable mostly for very large telescopes.
The ASI432MM uses a Sony IMX432 global shutter CMOS sensor. Its frame size is 1.1", with large 9.0μm pixels, 1.77 million pixels (1608 * 1104). In ADC 12-bit mode, it can output 120 frames per second at full resolution and has a read out noise level as low as 2.9e.
Large format, large FOV
ASI432MM has a large sensor format of 1.linch and hence a large field of view. The area is almost twice that of ASI174MM, making it a better choice for solar imaging and lunar imaging than ASI174MM which is an already recognized solar imaging camera.
Large pixels, high sensitivity
The 9um pixel size is almost 1.5 times larger than the ASI174MM pixel size. With its high sensitivity, images with finer colours and subtler details are now possible. You can have full trust in its solar imaging performance regarding to both full disk and local details.
m Global shutter Being a global shutter camera, ASI432MM also features a very high fps rate. Thus, it' s not only good for solar and lunar imaging, also suitable for you to photograph ISS and other fast-moving objects.
Full well depth
ASI432MM has a full well depth of 97ke, which is 3 times larger than that of ASI174MM. The larger full well depth provides the camera with stronger sensitivity. When we want to photograph the Sun surface and prominences at the same time, a very good quality image can be obtained.
Upgrade Iterative
The ASI432MM is an upgraded camera to the ASI174MM. Compared with ASI174MM, it has a larger frame and larger pixel size, providing users with a better choice for solar and lunar photography.
Readout Noise
Compared to traditional CCD cameras, the readout noise of ASI432 is extremely low. The built-in HCG mode can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 140, the HCG mode is automatically turned on and the dynamic range rises back to 12bit. When the gain is 400, the readout noise is 2.4e.
Quantum Efficiency
The QE curve and readout noise are the most important parameters for measuring camera performance. Higher QE, lower readout noise is a necessary condition to improve the signal-to-noise ratio.
Anti-Amp Glow Function
The anti-amp glow function which is independently developed by ZWO and is used in ASI cameras effectively limits the amp glow on sensors and maximises the cameras' photographic performance. Since it is implemented directly at the hardware level, it does not require software control.
