ChemiMOS 9
↳ Exceptionally low dark current
↳ No downtime for recalibration
The ChemiMOS 9 is a compact scientific CMOS camera designed for labs and OEM systems that demand repeatable low-noise data. At its core is Sony’s IMX533 (mono or color), a 3011 × 3011 square sensor with 3.76 μm pixels and a 15.968 mm diagonal (11.3 × 11.3 mm effective area).
Where many cameras force you to choose between footprint and flexibility, ChemiMOS 9 offers both: the standard model keeps the form factor lean for tight instruments, while ChemiMOS 9FW integrates a motorized filter wheel inside the body for turnkey multi-channel fluorescence or multispectral work – no extra opto-mechanics, no alignment headaches, and a single, stable optical path.
Clean backgrounds are everything in low-signal experiments. ChemiMOS 9’s sensor architecture is engineered for zero amp glow and very low read noise: 1.6 e⁻ (High Gain Mode) or 3.6 e⁻ (Low Gain Mode). Pair that with a dark current of just 0.0005 e⁻/px/s at −20 °C and you get ultra-clean frames even when exposures stretch to minutes or hours. For chemiluminescence, bioluminescence, weak fluorescence, or faint-object imaging, that means less background subtraction, fewer retakes, and higher statistical confidence per frame.
With >50,000 e⁻ full-well capacity, ChemiMOS 9 comfortably accommodates bright structures while preserving dim details, maintaining a deep dynamic range that is critical for quantitative science. The camera runs a 14-bit ADC and outputs in a 16-bit image mode, preserving compatibility with scientific file formats and analysis pipelines while safeguarding intensity precision for measurement workflows.
The thermoelectric system provides a 35 °C delta below ambient, keeping the sensor in a low-noise regime. Because dark current scales with temperature, holding the die cool and stable directly improves repeatability in long-duration and time-lapse experiments.
The camera supports an exposure range from 0.001 s to 24 hours with electronic rolling shutter. You can tune for fast snapshots (e.g., bright-field, alignment, and focusing) or for deep integrations (e.g., chemiluminescence and weak fluorescence) using the same instrument. A full-frame 12 FPS rate provides responsive live view, rapid focus checks, and efficient acquisition for dynamic protocols—without sacrificing the noise performance you need for final data.
