The QHY163M/C camera has a 1/1.8inch, 6 megapixel CMOS sensor with 2.4um pixels.  The maxium frame rate is 50FPS@6 megapixels.  It has both mono version and color version, USB 3.0 interface, two stage TEC, and 14-bit A/D.  Readout noise is 2.4e at low gain and 0.9e- at high gain. 

128MB DDR Buffer
The QHY178 has a built-in 128MB DDRII image buffer. The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted.  This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals.  This buffer also makes it possible to run multiple cameras on the same computer without USB transfer problems. 

Full Anti-Dew Solution
With more than a decade of experience designing cooled cameras, QHYCCD has applied this knowledge to the QHY178 camera.  The full anti-dew technology includes a sealed CMOS chamber with silicon gel tube socket and a heated chamber optical window.  This technology prevents dew from forming on the sensor itself, or on the chamber window, even in a high humidity environment.

Sony's Image Sensor Exmor R is a back-illuminated CMOS image sensor with improved sensitivity and noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It retains the advantages of CMOS image sensors such as low power consumption and high-speed operation while dramatically improving sensitivity.  With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor's light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens, and this has also been an important issue in the miniaturization of pixels and widening optical angle response.

A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.  However, compared to conventional front-illuminated structures, back-illuminated structures have historically caused problems such as noise, dark current, defective pixels and color mixture that lead to image degradation and also cause a decrease in the signal-to-noise ratio  To overcome this Sony newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure.  Additionally, Sony's advanced technologies such as high-precision alignment have addressed any color mixture problems.

Here is a thing you need notice,because of some reasons,this software for Mac version didn't attach a necessary library,you need add it by yourself.You can click here to download that library,and unzip it to /usr/local/lib,and if you have installed libusb library in /usr/local/lib,you don't need do this.
