Coating technology for controllable thermal, radar, and EMI signatures
HeiQ Xpectra is a transparent coating technology for multispectral signature management in defense applications. The system addresses thermal, radar, and electromagnetic signatures within a single, adjustable coating platform. Performance can be tuned to deployed conditions without altering the visual appearance of materials.
HeiQ Xpectra can be integrated into new manufacturing processes or applied as a retrofit on textiles, hard surfaces, and selected transparent substrates.

Advantages for defense and aerospace integration
Multispectral coverage
Manages signatures across NIR, MWIR, LWIR, and radar, with support for EMI shielding across different surfaces.
Coated vs. uncoated glass, with a heat source behind the surface
Tunable thermal signature
Across platforms and materials
Retrofit and OEM compatible for hard and flexible surfaces, and suitable for selected transparent substrates where optical transparency is required.
