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.

Low Noise + Wide Dynamic Range

Typical sCMOS noise is < 2 e⁻ (30 fps) with dynamic range up to 50,000:1—far exceeding traditional CCDs.

Fast Readout & Versatility

Parallel readout supports >100 fps for capturing fast events such as cell motion, fluorescence lifetime studies, and plasma dynamics.

Low-Light Performance

Back-illuminated sCMOS sensors achieve >95% QE from UV to NIR, with low fixed-pattern noise and cooling down to −30 °C for astronomy and other needs.

Application Scenarios & System Value

Ideal for fluorescence microscopy, astronomy, cold atom research, X-ray imaging, materials inspection, and industrial microscopy—delivering high sensitivity, precision, and adaptability.
