才注意到涂层不是传说中的金子，是铱锌氧化物(ITO)。。。

A coating of iridium-tin oxide gives the canopy a gold color and is used to reflect radar waves away from the inside of the cockpit.[6]

而且F-16 也是类似涂层

Polycarbonate laminate canopy transparencies with the new coating system passed stringent requirements for bird impact, optical performance and environmental durability, according to Brent Wright, PPG Aerospace platform business manager for military transparencies.

“PPG expects the new S-406 inner and S-220 outer coatings will offer F-16 jet operators canopy transparencies with greater durability and affordability,” Wright said.

The new system is available on PPG canopy transparencies in clear and reflective indium tin oxide (ITO) configurations, he said. PPG Aerospace produces the forward and aft canopy transparencies for F-16 A/B/C/D configurations at its Sylmar, Calif., USA, facility.

The original YF-16 prototype performed its first flight in 1974 equipped with transparencies by Sierracin/Sylmar Corp., and the company has produced them since. PPG acquired Sierracin/Sylmar in 2006.
