The QHY42 uses the Gsense400 Scientific CMOS sensor with extraordinary 95% peak QE, 79% UV QE and very good NIR response, plus extremely low read noise of 1.7e-. This camera is ideal for astronomical and biological science research.
Ultra Low Read Noise
The low read noise and high QE make it possible to achieve high SNR even when imaging dim objects. Only 5 photons produce a SNR>3.
Amplifier Glow Control
Reduces Glow Significantly Microlens - free array
QHYCCD has developed a unique technology to reduce it. As applied in the QHY42, the user may enable / disable this feature.No microlens array, avoiding the influence on photometry.
Large Pixel size
89ke- Full Well Capacity
The QHY42 has relatively large 11um pixels in a 2k x 2k array. The sensor size is 22.5mm x 22.5mm yielding a good field of view even at longer focal lengths.
USB3.0 / 10GigaE Custom Design
QHYCCD currently produces the standard USB3.0 version QHY42 with 24FPS frame rate. The high speed 10GigaE version is under development and will support 48FPS HDR (2K x 2K x 2 A/D channels with 4096 x 2048 12-bit output).
QHY42 HDR Standard Version
The standard version has 2-stage TE cooling and USB3.0 interface. Single channel output is 24FPS at 12-bits. Dual channel HDR output is 12FPS at 12-bits. (The 12FPS HDR version can be supply in late of 2018, the original version can be upgraded without cost).
QHY42 HDR 10GigaE Version
Currently under development, the 10GigaE version produces 48FPS with 2 x 12-bit dual channel outputs. (4096 x 2048 RAW HDR output)
QHY42 Customized Version
QHYCCD can supply the QHY42 CMOS sensor board plus the high performance FPGA based image calculation platform. Five different FPGA modes ensures maximum flexibility for the customized project.
