1. Features & applications
The HI640S is an ultra‑compact uncooled infrared thermal imaging module featuring a micro‑shutter and a compact 28×28×30 mm footprint. Designed for high‑performance thermal imaging, it offers dual detector options (640×480 17 μm or 640×512 12 μm) with industry‑leading sensitivity down to 25 mK. With ultra‑low power consumption (<1.5 W), multiple configuration choices, and a wide range of lenses and interfaces, the HI640S is the ideal solution for cost‑effective OEM assembly and integration in portable, miniaturized, and low‑power thermal imaging systems.
2. Product Features
- Ultra‑small form factor & ultra‑light weight: 28×28×30 mm size and only 40 g (without lens) enable seamless integration into space‑constrained devices.
- Ultra‑low power consumption: < 1.5 W typical, extending battery life in handheld and UAV applications.
- Ultra‑high sensitivity: ≤25 mK (for 12 μm) or ≤40 mK (for 17 μm) @ f/1.0 ensures superior thermal contrast and image clarity.
- Micro‑shutter technology: Provides reliable operation and consistent image quality across varying scenes.
- Dual high‑resolution detector options: Choose between 640×480 17 μm or 640×512 12 μm configurations to balance sensitivity and detail.
- Adaptive non‑uniformity correction: Maintains image uniformity without manual intervention.
- Flexible interface options: Digital video ports (BT.656/HDMI/RJ45, etc.) and multiple communication protocols (RS‑232/RS‑485/TTL/Peclo‑D) for easy system integration.
- Wide power input range: Accepts DC +4 V to +12 V, simplifying power supply design.
- Advanced image adjustment: Polarity (black/white hot, pseudo color), 1‑8× digital zoom (0.1× steps), brightness control, image flip, and customizable reticles.
- Rugged environmental performance: Operating temperature range from -40°C to +60°C (special) and meets GJB 150 vibration/shock standards.
