Core Material Overview
Airborne EOIR domes use four substrate materials, selected based on payload weight, working spectrum and high-altitude environmental durability
Lightweight Single Crystal Sapphire — Mohs 9 extreme hardness with excellent strength-to-weight ratio. Broadband transmission from visible to mid-IR, superior sand erosion and UV resistance. The standard material for high-altitude long-endurance UAV EOIR turrets requiring dual-band day-night operation.
Zinc Sulfide (ZnS) — Lightweight IR material transmitting 3–12μm with good environmental durability. Cost-effective choice for pure thermal imaging airborne payloads where visible-light performance is not required.
Zinc Selenide (ZnSe) — Higher LWIR transmittance than ZnS with lower absorption. Preferred for high-sensitivity long-wave infrared airborne detection and cooled thermal camera systems.
Fused Silica — Ultra-low weight with exceptional thermal shock stability and UV resistance. Ideal for visible + near-infrared airborne systems operating in extreme temperature cycling environments.

Frequently Asked Questions
Q1: Why lightweight dome matters for industrial UAV?
A: Extra payload weight will directly reduce flight duration. Our optimized low-weight sapphire dome balances optical performance and weight control for long-distance aerial missions.
Q2: Can you customize dual-band coating for visible light + LWIR thermal imaging?
A: Yes. We develop exclusive BBAR coating to boost transmittance in both visible and infrared wavebands, fit EOIR day-night dual surveillance turret systems.
Q3: Which substrate should I pick for drone airborne dome?
A: Lightweight sapphire is preferred for anti-abrasion high-altitude flight; ZnS/ZnSe are cost-efficient options if your system focuses purely on thermal infrared imaging.
Q4: Can you produce mini-size domes for compact drone turret?
A: Fully customizable. We can process small-diameter hemispherical & ellipsoidal domes to match miniaturized airborne EOIR payload structure limits.
Q5: Do you provide prototype samples for UAV system testing?
A: Yes. We offer small batch prototype samples for client performance verification before formal mass production orders.
