Frequently Asked Questions

Learn more about scientific CMOS cameras

A scientific CMOS (sCMOS) camera combines the strengths of CCD and CMOS technology, delivering ultra-low noise, high frame rate, wide dynamic range, and high quantum efficiency—ideal for scientific research and precision measurement.

Ultra-low read noise: sCMOS read noise approaches 1 e⁻, far outperforming traditional CCDs.
High frame rate: Parallel readout architecture supports 100 fps or higher.
Wide dynamic range: Captures bright and dark regions simultaneously with ratios up to tens of thousands to one.
Large field of view and high resolution: Suits high-resolution, wide-field imaging.

Most sCMOS sensors adopt a rolling shutter for high-speed line-by-line readout. Some support pseudo-global shutter via synchronized illumination for tear-free imaging.

They are used widely in biological microscopy, fluorescence imaging, fast object inspection, astronomy, X-ray imaging, cold atom research, and other precision-science scenarios.

EMCCD cameras excel in ultra-low light or long-exposure conditions.

sCMOS delivers greater value for high-resolution, high-speed imaging with low noise.

In-Depth Product Overview

sCMOS Sensor Architecture

Each pixel has its own amplifier and column ADC for parallel readout, enabling high-speed, high-SNR imaging. Dual gain channels and dual ADC designs further expand dynamic range and sensitivity.
