QHYCCD 294M Pro Monochrome CMOS Camera

QHY294M Pro Cooled Monochrome CMOS Camera

The QHYCCD QHY294M Pro is a premium-quality cooled monochrome camera with an impressive CMOS sensor. The QHY294M uses the popular SONY IMX492 BSI CMOS sensor, achieving the pixel number output necessary for 4K at 120 frame/s.

This back-illuminated 11.7-megapixel sensor is housed in a sealed chamber that is heated to prevent dew from building up on the sensor or window. The sensor also uses 4.63um pixels and has extremely low read noise of 1.0e.

QHY has designed the QHY294M Pro camera with two read modes. The first read mode reads the sensor as 11.7 megapixels, 4.63um pixels and 14-bits. The second read mode unlocks the on-chip binning, which allows the camera to yield 4x the number of pixels (47MP) in a 4/3" format back illuminated sensor, ultimately resulting in a very high QE, read noise, and dark current. All this with a great dynamic range!

This camera's cooling feature reduces dark noise in your images. This feature comes in handy when imaging on warm summer nights! The QHY294M imaging camera has two-stage TEC cooling and temperature regulation that allows temperatures to reach a maximum of -35C below ambient. QHY has also tackled the problem of dew that can form on your sensor or sensor window, especially on damp nights. The QHY294 sensor chamber is fully sealed to keep air out and includes a window heater to keep everything nice and dry.

A built-in 256MB DDR3 image buffer provides a safeguard against unexpected drops in data transmission. A frame buffer avoids lost frames during USB transfer by storing image data in the camera itself until it can be safely transmitted. Buffering will also make sure your video runs more smoothly when using a slower computer.

Setting up your optical train with the QHY294M is easy! It has the same body design and mechanical interface as the QHY163, giving you short back focus and plenty of spacer options.
