Its performance is defined by an 89% peak QE, a dual-mode readout system with noise as low as 0.85e-, and a deep 48Ke- full well. The camera's broad spectral response, from 200nm in the UV to 1000nm in the NIR, enables advanced applications in spectroscopy and biofluorescence, all while capturing full frames at up to 21fps.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eGsense9701 BSI Sensor: Capturing 1.3MP with 9.76µm Pixels\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY9701 is a scientific-grade Gsense9701 monochrome sensor with a back-illuminated architecture. The exceptionally large 9.76µm pixels provide a massive surface area for photon collection, maximizing signal in light-starved applications. The 1.3MP resolution (1280 x 1024) is optimized for scientific analysis where per-pixel sensitivity and signal-to-noise ratio are more critical than sheer image scale, making it ideal for spectroscopy and targeted microscopy.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUltra-Low Noise Floor: 0.85e- Read Noise and 89% Peak QE\u003c\/h3\u003e\n\u003cp\u003eThe QHY9701's electronics offer two distinct readout modes to match your imaging needs. The ultra-low noise mode achieves a read noise of just 0.85e-, allowing for the detection of the faintest signals just above the noise floor. For brighter targets, an HDR mode with 1.6e- read noise leverages the sensor's full 48Ke- well depth to deliver an impressive 89.5dB of dynamic range. This low-noise architecture, combined with a peak Quantum Efficiency of 89% at 610nm, ensures that nearly every incoming photon contributes to your final data.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBroad Spectrum Sensitivity: 200nm to 1000nm Response\u003c\/h3\u003e\n\u003cp\u003eA key capability of the QHY9701 is its remarkably wide spectral response, covering a range from 200nm to 1000nm. This sensitivity extends deep into the ultraviolet (UV) and well into the near-infrared (NIR) regions, far beyond the limits of standard visible-light cameras. This makes the camera a powerful tool for fluorescence imaging, material analysis, and spectrographic systems where critical data lies outside the visible spectrum.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCooled Operation: Dark Current Down to 0.08e-\/s\/p at -28°C\u003c\/h3\u003e\n\u003cp\u003eTo ensure clean data during long exposures, the QHY9701 incorporates an active thermoelectric cooling system. This system dramatically reduces thermal noise, suppressing dark current to a mere 0.08e-\/s\/pixel at a sensor temperature of -28°C. Compared to the uncooled rate of 40e-\/s\/pixel at 31°C, the cooling system provides the stable, low-noise foundation required for repeatable scientific measurements and the capture of extremely faint photon signals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow would the QHY9701's broad spectral response benefit a Raman spectroscopy setup?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe \u003cstrong\u003eQHY9701's\u003c\/strong\u003e sensitivity from 200nm to 1000nm is a significant advantage for Raman spectroscopy.
