SBIG Scientific CMOS Imaging Camera Monochrome Camera with Internal Shutter

The STC-428M Scientific CMOS imaging monochrome camera provides a high sensitivity, low noise 7-megapixel imaging experience in a compact package. This variation of this camera includes an internal mechanical shutter for taking dark frames.

The new STC-428-M scientific CMOS camera represents a major improvement over CCD technology. Compared with previous CCD models, the STC-428-M features higher sensitivity (78% QE versus 56%), significantly lower read noise (2.5 e- versus 9.3 e-), and 20X faster readout.

While a single exposure on the IMX428 sensor can equal CCD dynamic range, the combination of fast readout and very low read noise allows for stacking many shorter to produce a greater dynamic range than previously possible. The built-in StackPro capability can automatically divide your exposure into up to 16 shorter sub-exposures, and stack them inside the camera prior to download. This increases dynamic range without imposing greater processing requirements on the host computer.

Our SmartCooling active regulation maintains the sensor temperature to within 0.1C, and minimizes fan speed based on heat sink temperature for longer life and quieter operation.
