商品描述

 

QHY183M\C采用了1英寸SONY背照式IMX183,两千万像素高灵敏度芯片,像素尺寸2.4um,在两千万像素的全分辨率下可以获得19帧每秒的图像,具有放大器辉光抑制电路,能最大程度的减少CMOS的放大器辉光。-40C制冷温差,读出噪声低值一个电子。满阱电荷数为15-16ke.


典型应用:深空摄影,月面,太阳及行星摄影。

128MB DDRII 内置图像缓冲内存
QHY183M/C内置了128M的图像缓冲内存,与不带内存的相机相比,能够避免长曝光时间的时候的丢帧问题,同时能降低对拍摄电脑的要求,即使对于低配置的电脑,或者USB2.0的接口,也能流畅使用。

 

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.
