As the demand for compact, high-performance imaging systems grows across defense, industrial, and research sectors, Low-SWaP (Size, Weight, and Power) solutions have become essential. In this context, Low-SWaP SWIR (Short-Wave Infrared) lenses are playing a crucial role in enabling portable, power-efficient, and high-resolution imaging—especially for use in UAVs (unmanned aerial vehicles) and handheld devices.
The Need for Low-SWaP Lenses
In airborne and portable platforms, space and power are limited. Traditional SWIR lenses—often designed for lab or fixed installations—can be bulky and heavy, which makes them unsuitable for lightweight drones or battery-powered devices.
Low-SWaP SWIR lenses address this challenge by offering:
- Compact form factors for easier integration
- Lightweight construction using advanced materials
- Optimized optical design for minimal power loss and high throughput
- Mechanical ruggedness for field-ready reliability
Key Features of Low-SWaP SWIR Lenses
Compact Barrel Design
Fits into small gimbals, UAV payloads, or handheld enclosures without compromising image quality.
Athermalized Optics
Maintains focus and performance across a wide temperature range—critical for outdoor or high-altitude use.
Broadband AR Coatings
Anti-reflection coatings designed specifically for SWIR wavelengths improve transmission and reduce ghosting.
Precision Focus and Aperture Control
Some models offer motorized or manual control options for focus and iris, ideal for dynamic scenes and field operations.
Applications in UAVs and Portable Systems
- Military and Security: Covert imaging, target acquisition, and surveillance in degraded visual environments.
- Infrastructure Monitoring: Detecting leaks, cracks, or corrosion in pipelines and power lines.
- Search and Rescue: Seeing through fog, smoke, or darkness in emergency missions.
- Scientific Field Research: Monitoring vegetation health, water content, and material properties on the go.
