Product Details ＋

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 0.1ºC, and minimizes fan speed based on heat sink temperature for longer life and quieter operation.
