sMAX Series

Product Introduction

The sMAX series is designed for low-light and long-exposure scientific imaging, covering sensor configurations including GSENSE2020 BSI, GSENSE4040, and GSENSE4040 BSI, offering high-resolution options from 2K×2K to 4K×4K. All models feature dual-stage TEC high-efficiency cooling structure, with sensor operating temperature approximately 40 °C below ambient, combined with anti-condensation optical structure to ensure image stability and cleanliness during low-temperature long-exposure applications.

The cameras support USB 3.0 / Camera Link high-speed data links and 16-bit data depth, providing research-grade functions such as temperature control, free-running/external triggering, and software/hardware binning. Some models can achieve exposure times up to 3600 s with GPS time synchronization, suitable for fluorescence microscopy, spectral measurement, astronomical observation, semiconductor inspection, and gene sequencing applications.

Windows / Linux SDK (C/C++/C#/Python) and supporting software such as ToupView/CLView are provided for secondary development and system integration.

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.
