Thermal imaging systems allow users to visualize temperature differences that are otherwise invisible to the human eye. These systems are essential in critical applications ranging from emergency rescue and autonomous driving to energy audits and industrial inspection.
At the heart of every reliable thermal system is an optical lens designed to transmit infrared radiation with precision, clarity, and durability.
At Universe Kogaku, we engineer custom thermal imaging lenses that meet the demanding specifications of OEM designers and integrators building infrared-enabled systems across diverse industries.
Why Thermal Imaging Depends on Optical Precision
Thermal cameras work by detecting infrared radiation—typically in the 8–14 µm range—and converting it into an image. To capture this data accurately, the lens must:
- Transmit longwave infrared (LWIR) wavelengths without distortion
- Maintain sharp resolution across the entire sensor area
- Withstand temperature changes, shock, and vibration
- Match the system’s sensor format and field-of-view
Unlike lenses used in visible light systems, IR lenses must be made from materials like germanium or chalcogenide glass and designed to function within thermal bands.
Applications for Thermal Imaging Lenses
Firefighting & Emergency Response:
Thermal cameras help firefighters locate individuals through smoke, identify hot spots in structures, and monitor hazardous areas. Our lenses support rugged handheld and helmet-mounted systems.
Search & Rescue:
In mountainous or low-light environments, thermal imaging is used to locate lost or injured people. UKA lenses are designed for UAV and drone integration.
Autonomous Driving & ADAS:
Thermal sensors complement radar and lidar in autonomous vehicles. Our thermal lenses can be designed for fixed or dynamic focus, optimized for night driving.
Industrial & Preventative Maintenance:
Thermal imaging is used to detect failing equipment, leaks, and electrical anomalies. Our custom lenses operate reliably in factory and field service conditions.
Medical Imaging & Diagnostics:
Infrared cameras monitor vascular conditions, inflammation, and more. Our compact lens designs support safe, non-contact imaging for clinical use.
Energy Audits & Building Inspections:
Thermal cameras detect heat loss and insulation failures. UKA lenses ensure precision and repeatability in these applications.
Environmental & Geological Sensing:
From volcanic heat signatures to ecosystem changes, thermal imaging provides critical data. We offer IR-compatible optics for scientific and environmental tools.
