  • QHY9701 Cooled Scientific BSI CMOS Camera

    The QHY9701 is a cooled scientific camera built around the Gsense9701 back-illuminated sensor, featuring 1.3MP resolution and massive 9.76µm pixels for exceptional sensitivity. 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.

    Gsense9701 BSI Sensor: Capturing 1.3MP with 9.76µm Pixels

    At 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.

    Ultra-Low Noise Floor: 0.85e- Read Noise and 89% Peak QE

    The 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.

    Broad Spectrum Sensitivity: 200nm to 1000nm Response

    A 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.

    Cooled Operation: Dark Current Down to 0.08e-/s/p at -28°C

    To 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.

  • How would the QHY9701's broad spectral response benefit a Raman spectroscopy setup?

    The QHY9701's sensitivity from 200nm to 1000nm is a significant advantage for Raman spectroscopy. It can capture both the Stokes and anti-Stokes scattering lines, including signals that may fall in the UV or NIR regions, providing a more complete spectral analysis than a camera limited to the visible spectrum.

    For fluorescence microscopy of a faint biological sample, which QHY9701 noise mode should I use?

    For a faintly glowing sample, you should use the Low Noise mode. This mode's extremely low 0.85e- read noise ensures that the faint photon signal from your sample is not lost in the camera's own electronic noise, maximizing your signal-to-noise ratio and revealing finer details.

    What is the primary advantage of the QHY9701's large 9.76µm pixels?

    The primary advantage of the QHY9701's 9.76µm pixels is their large light-collecting area. This maximizes sensitivity and allows the camera to detect very faint signals quickly. It's a design choice that prioritizes signal strength over high resolution, making it ideal for applications like spectroscopy and low-light fluorescence imaging.

    Why is the QHY9701's back-illuminated (BSI) sensor important for its high QE?

    In a back-illuminated (BSI) sensor, the wiring layer is moved behind the photodiode. This prevents circuitry from blocking incoming photons, allowing more light to reach the light-sensitive silicon. This unobstructed path is a key reason the QHY9701 achieves its high peak Quantum Efficiency of 89%.

    How does the QHY9701's thermoelectric cooling impact long-exposure imaging?

    Thermoelectric cooling on the QHY9701 actively removes heat from the sensor, which drastically reduces thermal noise (dark current). By lowering dark current to just 0.08e-/s/p at -28°C, the cooling system ensures that long exposures are not contaminated by noise, resulting in cleaner data and the ability to detect much fainter signals.

    Is the QHY9701 suitable for general astronomical imaging of planets or deep-sky objects?

    While the QHY9701 has excellent sensitivity, it is not ideal for general astronomical imaging. Its 1.3MP resolution is low for capturing wide deep-sky vistas, and its electronic rolling shutter can introduce artifacts on planets during moments of unsteady atmospheric seeing. It is a specialized scientific instrument designed primarily for applications like spectroscopy and photometry.
