Description
Zhe Wu and co-authors published a study in 2026 on a film that swallows infrared light. Small optical gear needs a way to kill stray light without bulky baffles or deep cooling. The team built a layered film less than a micron thick on a bendy plastic base.
A lossy iron oxide layer inside the stack broadens what the film can absorb. Across a key band used by heat cameras, the film took in about ninety-seven percent of light on average. Stacked as a tube inside a test camera, it cut stray light to under one percent after three bounces. The film survived bending tests and can be made by scalable pattern steps. The authors pitch it as a platform for small, flexible optics.
