Is the Reign of EMCCD Cameras Over? SinceVision’s Solis B518 Ushers in a New Era for Ultra-Low-Light Imaging
Imagine capturing the faintest whispers of light with unprecedented clarity. In the world of scientific research, where every photon counts, the choice of detector can make or break an experiment. Fields like quantum physics, life sciences, and materials science rely heavily on sensors that can detect single photons, track subcellular movements, and monitor molecular changes in real time. For decades, EMCCD cameras have been the go-to tool for these tasks. But here’s where it gets controversial: their limitations—such as aging, noise from electron multiplication, slow sampling rates, and high costs—have increasingly become bottlenecks for long-term studies and high-resolution analysis. Could there be a better alternative?
Enter the SinceVision Solis B518, a scientific sCMOS camera designed to thrive in the most demanding environments. This innovative device isn’t just another camera; it’s a game-changer that directly addresses the shortcomings of EMCCD technology. With its advanced chip design, low-noise electronics, vacuum sealing, efficient cooling system, and sophisticated image correction pipeline, the Solis B518 redefines what’s possible in low-light imaging across diverse scientific disciplines. And this is the part most people miss: it’s not just about improving performance—it’s about enabling entirely new types of experiments that were previously out of reach.

Extreme Sensitivity: Capturing the Unseen
At the heart of the Solis B518 is a custom back-illuminated CMOS chip (learn more). This design allows more light to reach the sensor while maintaining high quantum efficiency across both near-infrared and ultraviolet wavelengths. The result? Enhanced signal quality in ultra-low-light conditions, faster readout speeds, and reduced power consumption. But here’s the kicker: its large 18×18 μm pixels significantly expand the light-collecting area, making it far more sensitive than traditional cameras. In a flame test at 890 nm (see details), the Solis B518 produced a brighter image with just one-tenth of the exposure time required by a camera with 6.5 μm pixels. This isn’t just an improvement—it’s a revolution in sensitivity.

Sub Electron Readout Noise: When Every Photon Matters
The Solis B518 is engineered from the ground up to excel in ultra-low-light conditions. Its architecture—from sensor layout to electronic processing—is meticulously designed to minimize noise. Under EMVA 1288 testing (view standards), the camera achieves readout noise close to 0.5 electrons, placing it in an elite category for experiments where every photon is critical. But here’s a thought-provoking question: could this level of precision open doors to discoveries we haven’t even imagined yet?

Spatial Photon Number Resolution: Seeing the Invisible
Many sensors struggle to detect subtle changes in photon count because their readout noise obscures the signal. The Solis B518, however, boasts exceptionally low noise, enabling clear photon counting and superior spatial photon number resolution. Tests reveal an average output of about 3 electrons per pixel, with imaging noise following a Poisson distribution—a hallmark of accurate photon statistics in low-light environments. And this is where it gets fascinating: this capability could transform how we study phenomena like single-molecule interactions or quantum entanglement.

Very Low Dark Current Noise: Stability in the Shadows
Dark current, which increases with temperature and exposure time, can distort image baselines and amplify noise. The Solis B518 tackles this with multi-stage cooling capable of reducing temperatures by at least 60°C, coupled with vacuum sealing that achieves a leakage rate of 10⁻⁹ Pa·m³/s or lower. At -30°C, the dark current drops to a mere 0.007 electrons per pixel per second, ranking it among the best in its class. But here’s the real innovation: a patented algorithm stabilizes gray values during long exposures, ensuring consistent and reliable imaging across frames.

Strong Uniformity and Linearity: The Foundation of Precision
Dark signal nonuniformity (DSNU) measures pixel consistency in darkness, with lower values indicating more stable images. The Solis B518’s correction algorithms reduce DSNU to just 0.3 electrons, enhancing uniformity, minimizing random noise, and preserving linear response—critical for accurate scientific measurements. And this is the part most people miss: this level of uniformity isn’t just about better images; it’s about trust in the data.

A Foundation for Trace Level Imaging
The Solis B518 sets a new benchmark for capturing faint scientific signals with unparalleled clarity and stability. Whether you’re studying quantum phenomena, tracking cellular dynamics, or analyzing material properties, this camera provides the precision and reliability needed to push the boundaries of research. But here’s the ultimate question: will the Solis B518 become the new standard in ultra-low-light imaging, or will EMCCD cameras still hold their ground? Let us know your thoughts in the comments!
