QHY183C两千万像素背照式制冷CMOS相机

背照式CMOS 
 
背照式芯片是高灵敏度,高量子效率的同义词,背照式成像技术将像素上方的电路和电极放到像素背面,从而避免了光线的反射和损失。背照式的CCD广泛应用于专业天文台,但价格极其昂贵,可望而不可即,而QHY183C背照式CMOS相机不仅延续了背照式CCD的高灵敏度特性,还具有低至1个电子的超低读出噪声,具有优秀的性价比,是大家梦寐以求的高性能产品。

Sony's Image Sensor Exmor R is the 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 has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation
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 commonly causes 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 has 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.
