QHY42 PRO [MONOCHROME / UV]
QHY42 PRO [MONOCHROME / UV] - FSI is not in stock but it can be backordered.
The QHY42 PRO-BSI uses the Gsense400 Scientific CMOS sensor with extraordinary 95% peak QE, 79% UV QE, and very good NIR response, plus an extremely low read noise of 1.7e-. The QHY42 has relatively large 11µm 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. This camera is ideal for astronomical and biological science research.

In addition to the BSI version, QHYCCD also supplies the QHY42PRO-FSI version.
The standard version has 2-stage TE cooling and a USB3.0 interface. The camera has three readout modes: single 12-bit high gain channel output, single 12-bit low gain channel output, and Dual 12-bit high gain and low gain output mode. Single channel output is 24FPS at 12-bits. Dual-channel HDR output is 12FPS at 12-bits.
QHY42 PRO includes GPS / Trig Signal interface. It can output the precise exposure starting/ending waveform for external measurement. It can also connect with QHYCCD GPS-BOX to measure it. The QHYCCD GPS-BOX will output the timestamp onto the image head of each frame.

For BSI version, there are three types of the coating for the sensor - TVBIS, UV, VIS. The TVBIS is the most popular type and it has the best QE at 95%. The UV version has a peak QE of 79% at 275nm, while the TVBIS version has also a high UV QE at 240nm. For UV application, both TVISB and UV can be used, depending on the desired sensitivity. The TVISB version also has lower dark current than UV version.
The third VIS version is not as popular and the sensor is not as readily available, so contact us if you require the VIS version.
