pco.edge 3.1 | scientific CMOS camera

sCMOS是新一代科学级成像芯片，zui低可探测到10个光子。sCMOS在普通CMOS的技术上进行双路读出，双路独立放大，再分别进行数模转换，每路输出11bit数字图像，然后两路11bit图像重构成16bit的高动态图像。sCMOS继承了CMOS的5T技术，同时在像元上增加了微透镜，且采用片上CDS技术，减少了暗电流及读出噪声，split读出机制更使sCMOS芯片同时具备了高灵敏、高动态、高分辨、高帧频、低噪声的特点。sCMOS还具体*的结构设计，采用双路读出，双路放大、双路输出后分别进行数模转换，然后重组成高动态范围的图像，因此具备了CMOS的高分辨率，高帧频，还具备了高灵敏、低噪声、高动态等特点。

rolling shutter readout modes - optimized for synchronization of microscopes and scanning applications

All pco.edge sCMOS cameras from the beginning feature a variety of precise synchronization modes,which are optimized for advanced microscopy imaging and scanning. The flexible frame and line triggers
with very low latency in combination with the free selectable readout modes can easily be combined to cover every modern microscopy situation
to name a few:

• lightsheet microscopy
• selective plane imaging microscopy (SPIM)
• structured illumination microscopy
• localizations microscopy(GSD, PALM, STORM, dSTORM)
• spinning disk confocal microscopy
• RESOLFT

For example, one mode is used in a lightsheet or SPIM application, the lower right rolling shutter operational mode “single top down” operation is convenient to properly synchronize the camera exposure with the scanner. On the other hand,if speed is required and a flash like exposure is applied the upper left mode “dual outside in” is used for localization microscopy techniques like GSD, PALM or STORM.

superior image quality
The new pco.edge camera (with scientific CMOS image sensor) features outstanding low read out noise of 1.1 electrons (e-) med. Even at maximum speed of 50 frames/s at full resolution of 2048 x 1536 pixel
the noise is 1.1 e- med. Moreover the pco.edge provides an excellent homogeneous pixel response to light (PRNU, photo response non-uniformity) and an excellent homogeneous dark signal pixel behaviour
(DSNU, dark signal non-uniformity), which is achieved by a sophisticated electronic circuit technology and firmware algorithms. The lower figure shows a comparison of a scientific grade CCD and the new pco.sCMOS image sensor under similar weak illumination conditions. This demonstrates the superiority of pco.sCMOS over CCD with regards to read out noise and dynamic, without any smear (the vertical lines in the CCD image).
