The QHY174GPS camera uses the 1/1.2-inch SONY IMX174 CMOS sensor with global shutter, 5.86um pixels,138FPS@1920*1200, high QE of 78%, and low read noise of 3-5e-. Unlike a rolling shutter, a global shutter guarantees that the exposure time for the whole image area is uniform, beginning and ending at exactly the same time. This type of shutter is ideal for high precision time-domain applications.
The QHY174GPS has a unique built-in GPS module that can sync with the atomic clock signals received from GPS satellites. The QHY174GPS can record the start and end of exposure time with 1us precision anywhere on earth. The QHY174GPS was selected by the NASA New Horizons Team to successfully captured the MU69 occultation in the Summer of 2017.
The QHY174GPS uses 2-stage TEC cooling to significantly reduce dark current.
The IMX174 sensor normally has significant amplifier glow which will affect the entire image area in exposures of any significant length. However, QHYCCD has successfully incorporated our unique amplifier glow reduction technology into the design of the QHY174GPS camera to yield excellent results with this sensor.
