4.1. Sensor Technology: One Inch Square Frame

The ASI533MM-Pro utilizes the IMX533, a 1-inch square frame CMOS image sensor. This sensor features approximately 9 effective megapixels with a pixel size of 3.76µm. Its 14-bit digital output allows for high-speed signal readout at 20 frames per second with low read noise (as low as 1.0e). The performance of the IMX533 is comparable to SCMOS or EMCCD sensors, making it ideal for imaging needs requiring high definition and low noise.

Figure 4.1: IMX533 1-inch square frame sensor details.

4.2. 2-എസ്tagഇ TEC കൂളിംഗ്

The camera features a 2-stage thermoelectric cooler (TEC) capable of cooling the CMOS sensor to 35°C below ambient temperature (based on a 30°C ambient temperature test result). This significant temperature reduction greatly minimizes dark current, thereby improving the signal-to-noise ratio, especially during long exposures lasting hundreds of seconds.
