- Ultra-high frame rates: 108 fps (CameraLink) / 89 fps (USB 3.0)
- Dual cooling system reducing thermal noise (35-40°C below ambient)
- High dynamic range mode (91.8dB) with 16-bit digitizer
- Anti-fog heating structure for low-temperature environments
- Precision external 7-Pin I/O trigger synchronization
Thermoelectric Cooling (TEC) & Heated Anti-Fog
Equipped with an advanced thermoelectric cooling structure to achieve a temperature drop of up to 40°C. An integrated heated glass anti-fog window prevents sensor surface condensation in cold or humid environments.

Back-Illuminated (95% Peak QE)
Quantum Efficiency (QE) & Noise
Quantum Efficiency (QE) measures a sensor's effectiveness in converting incoming photons into electronic signals (photoelectrons).
Traditional Front-Illuminated (FI) cameras have wires on top of the silicon, blocking light and reducing QE to ~50%.
High-end Back-Illuminated (BSI) cameras flip the silicon substrate to expose it directly to light, raising QE to an incredible 90%–95%. This enables detection of faint fluorescence and astronomy subjects that would be lost under the noise floor of low QE sensors.
Simulator Controls
💡 Scientific Impact
A 95% QE camera halves the required exposure time or excitation laser intensity compared to a 50% QE sensor, reducing sample phototoxicity and photobleaching.
