sCMOS(scientific Complementary Metal–Oxide–Semiconductor) are a type ofCMOS image sensor(CIS).[1]These sensors are commonly used as components in specific observational scientific instruments, such asmicroscopes[2]andtelescopes.[3]sCMOS image sensors offer extremely low noise, rapidframe rates,widedynamic range,high quantum efficiency,high resolution,and a large field of view simultaneously in one image.[4][5]
The sCMOS technology was launched in 2009 during theLaser World of Photonicsfair in Munich. The companiesAndor Technology,Fairchild ImagingandPCO Imagingdeveloped the technology forimage sensorsas ajoint venture.[6][4]
Technical details
[edit]Prior to the introduction of the technology, scientists were limited to using eitherCCDorEMCCD cameras,both of which had their own set of technical limitations.[7]While back-illuminated electron-multiplying CCD (EMCCD) cameras are optimal for purposes requiring the lowest noise and dark currents, sCMOS technology's higher pixel count and lower cost result in its use in a wide range of precision applications. sCMOS devices can capture data in a global-shutter “snapshot” mode over all the pixels or rectangular subsets of pixels, and can also operate in a rolling-shutter mode.[8][1]
The cameras are available with amonochrome sCMOS image sensorsor withRGB sCMOS image sensors.With sCMOS, digital information for each frame is generated rapidly and with an improved low-light image quality. The sCMOS sensor's low read noise and larger area provides a low-noise, largefield-of-view(FOV) image that enables researchers to scan across a sample and capture high-quality images.[9][5]
Some disadvantages at this time, (2023), with sCMOS cameras versus related technologies are:
- sCMOS sensors tend be more expensive than traditional CMOS sensors.
- sCMOS sensors have a limited resolution compared to other types of sensors like CCD.[10]

In practice
[edit]TheNew York University School of Medicineuses sCMOS cameras for their research. They were used to study biological molecules and processes in real-time atnanometer scale.[1]Such cameras were also in use in astronomy andmicroscopy.[11]
