2025/11/24In November 2025, the Society for Neuroscience (SfN) Annual Meeting—Neuroscience 2025—was held at the San Diego Convention Center. Tucsen showcased a portfolio of high-performance scientific cameras engineered for the demands of modern neuroscience research. Among them, the Aries 6504 and Leo 5514 Pro stood out, combining high sensitivity with high-speed imaging to deliver exceptional technical performance and strong application potential across a wide range of neural imaging workflows.
Aries 6504:Ultra-Sensitivity and High speed Imaging
Neuroscience experiments involving neurotransmission imaging, deep-brain fluorescence detection, or fast physiological dynamics often operate under extremely low photon conditions. Under these conditions, image signal-to-noise ratio (SNR) and high-speed acquisition become critical.
Designed for these low-light regimes, the Aries 6504 sCMOS camera offers:
● Read noise as low as 0.43 e-
● Frame rate of 300 fps@4.2 MP
● 0.001e-/p/s ultra-low dark current
This level of sensitivity enables clearer visualization of subtle physiological events previously buried in electronic noise—benefiting studies of neurotransmitter release, deep-brain fluorescence imaging, and high-speed functional imaging.

Leo 5514 Pro：Large FOV & Ultra High-Speed Imaging
Systems neuroscience increasingly requires imaging tools that combine high spatial resolution with fast temporal sampling to capture distributed neural activity across extended brain regions.
The Tucsen Leo 5514 Pro camera offers the following technical advantages:
● BSI global shutter architecture for distortion-free imaging
● 14 MP resolution supporting a 30.5 mm large FOV
● Up to 670 fps full-frame for rapid functional dynamics
The global shutter design eliminates rolling-shutter artifacts, ensuring accurate capture of fast events such as propagating activation waves or optogenetically evoked responses.
A Portfolio Supporting Diverse Scientific Imaging Workflows
Leo 3243 / 3243 Pro – Fast sCMOS with Rolling Shutter
Built on a stacked BSI sCMOS architecture, the Leo 3243 / 3243 Pro series features 3.2 μm pixels, a rolling-shutter design, and up to 100 fps at 43 MP. These capabilities make it well-suited for high-resolution, low-light cellular imaging applications that require fine spatial detail.
