Overview

The Aries 6504 Pro is built on a next-generation back-illuminated sCMOS platform, delivering substantial improvements in readout noise, frame rate, and dark current. In high-sensitivity readout mode, it achieves 0.43 e⁻ (RMS) readout noise for single-photon-level signal discrimination, complemented by 297 fps at 4.2 MP in high-speed readout mode and a dark current of ≤0.01 e⁻/pixel/s @ −20 °C. Together, these capabilities extend the performance envelope of sCMOS cameras for demanding low-light and high-speed imaging applications.

95% QE & 0.43e-(RMS)
Single-Photon-Level Resolution

The Aries 6504 Pro is optimized on a back-illuminated sCMOS platform with 95% QE and 6.5 μm pixels. In high-sensitivity readout mode, it achieves 0.43 e⁻ (RMS) readout noise with 99 fps at 4.2 MP. Photon probability density fitting over 100,000 frames shows distinguishable photon distributions, supporting quantitative and stable measurements at extremely low photon levels.
297 fps @ 4.2 MP
High-Speed with Sub-Electron Noise

In high-speed mode, the Aries 6504 Pro operates at up to 297 fps at full 4.2 MP resolution, representing a threefold increase in frame rate compared with previous-generation sCMOS cameras of the same sensor format. Sub-electron readout noise down to 0.8 e⁻ is maintained at full resolution, enabling efficient photon utilization in high-speed, low-light conditions.
170 fps @ 16bit
High Speed & High Dynamic Range

The high dynamic range mode supports 170 fps at 4.2 MP, combined with a full well capacity of up to 15 ke⁻ and true 16-bit digitization. This allows accurate capture of both low- and high-intensity signals within the same acquisition, supporting quantitative imaging across a wide dynamic range.
0.01 e-/pixel/s @ −20 °C
Low Dark Current for Long-Exposure

At −20 °C, the Aries 6504 Pro exhibits a dark current as low as 0.01 e⁻/pixel/s, approximately one-fifth that of previous-generation 6.5 μm sCMOS cameras. This reduction significantly improves long-exposure performance and supports applications requiring extended integration times under low-light conditions.
