In precision inspection, clarity isn’t just expected — it’s essential. Whether you're analyzing semiconductor stacks, identifying contamination on a food line, or spotting micro-defects in solar cells, your imaging system needs to deliver flawless results. For users of SWIR (Short-Wave Infrared) cameras, that level of accuracy depends on one key factor: sensor temperature stability.
Until now, achieving that stability came at a cost.
The Thermal Trade-Off
SWIR cameras often rely on Thermoelectric Cooling (TEC) to regulate their sensors. While TECs help cool the sensor itself, they also cause the overall internal camera temperature to rise — limiting performance, reducing sensor stability, and introducing thermal noise over time.
The result? Heat buildup that directly impacts image quality, especially during continuous or high-speed inspection cycles.
Enter AirJet®: Solid-State Cooling That Stabilizes Everything
The integration of AirJet® changes the game.
By actively removing heat from the camera housing — without fans, vents, or moving parts — AirJet® keeps the entire system cool. This improves TEC efficiency and prevents thermal drift, allowing the sensor to maintain its ideal temperature for longer periods.
In test systems, AirJet® reduced sensor temperature from 45°C to just 15°C — dramatically improving thermal stability and enabling sharper, more consistent imaging throughout extended operations.
Before vs. After: What Changes for the End User
Where It Matters Most: Real-World Applications
CREVIS, a leading manufacturer of machine vision cameras for global industrial applications, is an early adopter of the AirJet Mini Gen 2. “As a leader in industrial machine vision, it's essential that our products meet the latest demands of our customers,” said Mr. Jun-Heoun Hwang, CEO of CREVIS. “By integrating the AirJet Mini Gen 2 into our cameras, we’re able to achieve better image quality with lower noise, higher frame rates, and still maintain a compact and cool design. For a long time, heat issues had limited our performance — but this incredible technology helps us overcome those barriers. It’s a true game-changer and a key differentiator for us in the market.” Pictured: Crevis’ CoaXPress.
