At present, the global drone market is growing rapidly. According to relevant data reports, the global drone market has exceeded 100 billion US dollars (with a compound annual growth rate of 18.7% in 2025). Therefore, the weather resistance requirements for key components of drones have also increased sharply, such as dronesCamera lens protective glass (suspended compartment)Protect window lenses）.

01

Pain points of traditional drone lens protective glass

Traditional drone lens protective glass has three major pain points:Surface wear in dusty environmentsOn average, 0.3mm scratches are generated every 200 flight hoursTransmittance attenuation caused by extreme temperature difference(Decay up to 15% under operating conditions of -20 ℃ to 60 ℃)Atomization phenomenon caused by chemical corrosionThe drone failure rate in coastal areas has increased by 40%. This makes it necessary to avoid these issues in the material properties of the protective glass for drone lenses.

The advantages of using sapphire glass as protective glass for drone cameras

1. Superb hardness, sapphire has a Mohs hardness of level 9, second only to diamond, and has a scratch resistance 6 times higher than traditional tempered glass, which can withstandHigh-speed sand particlesto attack; 2. GoodOptical transmittance(covering ultraviolet to infrared)The infrared band transmittance is 12% higher than that of ordinary glass, and can support the non-destructive transmittance requirements of 8K camera systems; threeGood resistance to high and low temperature working range；Chemical inertness traitCan resist corrosion from salt spray and acid rain. Finally, the lightweight design of sapphire glass also has significant advantages.
