Head-mounted thermal imagers

InfiRay & FLIR Helmet-Mounted Thermal Monoculars — Hands-Free Thermal Imaging Systems

A helmet-mounted thermal imager provides hands-free target detection and situational awareness, allowing operators to manipulate weapons, steer vehicles, and navigate in zero-light conditions without losing sight picture. This category features purpose-built tactical thermal monoculars from InfiRay and FLIR.

InfiRay (iRay) designs ultra-compact systems across its MINI (MH25, ML19) and versatile RICO MICRO (RH25, RL25) series. These feature lightweight composite housings engineered for rapid one-handed detachment and direct integration into standard night vision helmet mounts. FLIR’s Breach series is built around the proprietary FLIR Boson thermal core, delivering high thermal contrast and structural resilience for mission-critical identification. InfiRay provides a field-proven balance of reach and affordability for dynamic maneuvers, while FLIR Breach serves applications prioritizing thermal clarity and ruggedness.

Deploying a hands-free thermal system requires matching mounting interfaces: dedicated J-arm adapters, bridge mounts, and helmet shrouds compatible with specific housing footprints, alongside modular 18650/16340 battery configurations for extended field operations.

Key Technical Features

• Uncooled Microbolometer Cores: Instant-on operational readiness requiring no internal cooling cycles.

• Thermal Sensitivity (NETD): Sub-20 to 25 mK thermal ratings with 12 $\mu$m pixel pitch for precise target resolution through smoke, dust, and foliage.

• Field-Swappable Power: Powered by standard 18650 or CR123A batteries for rapid maintenance without specialized tooling.

• Ingress Protection: Rugged IP67-rated waterproof and dustproof housings ready for harsh field environments.

• Versatile Helmet Mounting: Direct compatibility with J-arm, Dovetail, and Wilcox-style interfaces via dedicated adapters for InfiRay MINI, RICO MICRO, and FLIR Breach.

• Fast Germanium Optics: Fast F1.0/F0.9 optical assemblies ensure maximum infrared photon gathering on compact objective lenses.

• Reinforced Mount Hardware: CNC-machined anodized aluminum, stainless steel, and high-strength polymer brackets eliminate play during dynamic movement.

• Firmware & App Integration: Direct smartphone app connectivity (such as InfiRay Outdoor) for live streaming, recording, and firmware upgrades.
