It achieves a peak Quantum Efficiency of 77% at 1200 nm, capturing faint signals well beyond the range of silicon-based sensors. To manage the inherent dark current of its InGaAs sensor, a powerful hybrid cooling system provides regulated cooling down to 35°C below ambient on air or up to 80°C below ambient with liquid coolant.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSony InGaAs Sensor: 77% QE from 400 to 1700 nm\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY990 PRO II is a scientific-grade Sony InGaAs sensor designed for high sensitivity across a wide spectral range of 400 nm to 1700 nm. With a peak QE of 77% at 1200 nm, this camera excels at applications requiring detection in the near-infrared. The sensor's Cu-Cu interconnect technology results in very low Fixed Pattern Noise (FPN) and a low defect pixel ratio, ensuring clean and uniform data for precise measurements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHybrid Cooling: Down to -80°C Below Ambient for Low-Noise SWIR\u003c\/h3\u003e\n\u003cp\u003eInGaAs sensors inherently produce more dark current than their silicon counterparts, making aggressive cooling essential for scientific imaging. The QHY990 PRO II addresses this with a flexible hybrid cooling system. Standard air cooling achieves a delta of 35°C below ambient, while the liquid cooling circuit can reach 45°C below ambient with tap water or as low as 60°C to 80°C below ambient with a chilled liquid supply, dramatically reducing thermal noise for long exposures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eLab-Ready Integration: Dual 10GbE, C-Mount, and 25mm Filter Support\u003c\/h3\u003e\n\u003cp\u003eDesigned for seamless integration into scientific and industrial systems, the QHY990 PRO II features robust connectivity options.
