QHY4040 FSI Cooled Scientific Cameras (CMT, CMN)
Large Area Sensor, 36.9 x 36.9mm 4K x 4K
The QHY4040 uses a GSENSE4040FSI front-illuminated, 16.8 Megapixel, 36mm square, scientific CMOS image sensor. With a five transistor (5T) HDR pixel design and a 9μm pitch, the sensor can achieve 3.7e- read noise and 74ke- full well capacity in HDR mode. The QHY4040 camera achieves 20 FPS at full resolution with USB 3.0. This makes the QHY4040 an ideal camera for various applications. The GSENSE4040 sensor is offered in two variations: CMN and CMT. CMN is a monochrome sensor without microlens array and is protected by a removable glass lid, which is ideal for X-ray imaging, charged particle detection, and micro-CT application; while CMT is a monochrome sensor with microlens array and sealed with D263T lids with anti-reflective coating on both sides, ideal for medical imaging and astronomy applications.
Multiple Pixel Clocks, 20 FPS at Full Resolution
The QHY4040 has a USB3.0 high-speed interface with up to 5GB of bandwidth. The camera achieves 1:1 video output at 20 frames per second (8-bit) with 4096 x 4096 resolution or 8FPS in low noise 12-bit mode. As different clock rates affect read noise performance, the QHY4040 supports five readout clocks and 8FPS, 12FPS, 16FPS, 18FPS and 20FPS frame rates.
74% QE, 86dB Dynamic Range, 3.7e- Read Noise
Currently, the QHY4040 is only available in a front illuminated version. A back-illuminated version of this sensor is rumored to be available in the future. In general, the fan-blade mechanical shutter will be broken if it is used 200,000 times or so, and in some specific cases it is easy to fail to switch on or off. The advantage of electronic shutter over mechanical shutter is high reliability and stability when the observatory shoots a large number of pictures. The electronic shutter is a relatively perfect choice for the observatory. The QHY4040 has an ultra-high dynamic range of 86dB and an extremely low readout noise of 3.7e-. This makes the camera exceptional for astronomical imaging, medical imaging, life sciences, fluorescence detection, trace sciences.
Dual Stage Regulated TE Coolling -35C
The QHY4040 has 2-stage thermoelectric cooling that reduces the sensor temperature to -35 °C below ambient. TE cooling significantly reduces dark current and produces cleaner, lower noise images over long exposures.
Astronomical Imaging, Biological Imaging, X-Ray Imaging, Dynamic DR
The high sensitivity, large field of view, 9um pixel size and large dynamic range are all ideal for astronomical imaging. The large 36.9mm x 36.9mm sensor with high resolution, high quality Image output also makes the QHY4040 ideal for Biological imaging. For dynamic medical x-ray DR imaging the QHY4040 sensor size matches most industry-standard DR lenses and the high frame rate and low readout noise performance is ideal for X-ray imaging.
