Brand: QHYCCD / SKU: QHY-4040FSI-PRO-I (110082)

QHY4040/QHY4040PRO is a scientific cooled CMOS camera with GSENSE4040 4K*4K sCMOS sensor. It has a 36.9mm x 36.9mm square sensor with 9.0um pixels in a 4k x 4k array. It has a 36.9*36.9mm big image area. 9um pixel size.

QHY4040/PRO has both the FSI version and BSI version. FSI version has a peak QE of 74%, 70ke full-well (at the lowest gain), 4e readout noise (at the highest gain). BSI version has a peak QE of 90%, 39ke full-well (at the lowest gain), 2.3e readout noise(at the highest gain), and a wide spectrum from UV to Near IR.

QHY4040 has only the FSI version, supports a single 12BIT channel readout (high gain channel only). QHY4040PRO has both FSI version and BSI version, supports selectable dual 12bit channel output (high gain, or low gain), and also supports the on-camera dual 12bit to 16bit data combination process.

The standard version is two-stage TEC cooling with air cooling. QHYCCD can provide the water cooling version as requested.

The typical application of this camera is astronomy imaging, spectrum, dynamic x-ray DR, satellite tracking, etc. Contact us if you are interested in the LQ version.

SHIPPING NOTE: Shipping cost will be determined after the order is made and must be paid before the camera will ship. A shipping quote can be obtained on request.

About This Product

QHY's Fiber Grabber Card is a PCIE2.0 x 8 image data graber card. It supports 2*10Gbps high-speed optical communication between the camera and the computer. A single QHY PCIE Grabber card can be used with more than one camera in succession (not simultaneously). This means that if you have multiple QHY PRO series cameras, and you plan on using them at different times, then you only need one card between them.


  • PCIE 2.0 x8
  • 4GByte onboard DDR3 memory
  • Four 10Gbps fiber sockets
  • One 40Gbps fiber sockets

Supports the following cameras:

QHY268PRO, QHY600PRO, QHY461, QHY411, QHY4040PRO
