CMOS & sCMOS
CMOS and sCMOS cameras are a more recent development in silicon imaging technology where the amplifier circuitry is built into the pixel, enabling parallel processing of the pixels and higher frame rates than their CCD brethren. The downside to having the extra circuitry at each pixel site is less than 100% fill factor and lower quantum efficiency. To compensate, most CMOS sensors use microlenses to focus the incoming light onto the sensitive area of the pixel.
Recent advances in CMOS manufacturing techniques have yielded back-illuminated sensors, with 100% fill factor and similar quantum efficiency to CCDs.
CMOS cameras range from 1 megapixel to 10’s of megapixels, with pixel sizes from 4um to 11um. Readout of the pixels is either in rolling shutter mode (each line is exposed consecutively) or global shutter (all lines are exposed simultaneously). Experimental parameters such as binning and readout speeds is generally more limited than CCDs.
We offer sCMOS and CMOS cameras from Princeton Instruments, IO Industries, Thorlabs and New Imaging Technologies.
We are able to provide board level and customized OEM solutions.
