Core Pain Points We Solve
Standard half-sphere domes have limited field of view and leave blind monitoring areas
Ordinary dome surfaces produce severe edge distortion for wide-angle optical imaging
Plastic and low-grade glass domes scratch easily in airborne & marine working environments
Few suppliers provide professional optical simulation for custom hyper-hemisphere outlines

Core Material Overview
Hyper hemispherical domes support four major substrate materials, selected based on working spectrum, FOV distortion requirements and environmental durability
Single Crystal Sapphire — Mohs 9 extreme hardness, broadband transmission from UV to mid-IR, excellent scratch and salt-fog resistance. The standard material for outdoor, airborne and marine panoramic hyper domes requiring long-term durability.
BK7 / H-K9L Optical Glass — Cost-effective visible-light substrate with excellent polishing precision and low edge distortion. Suitable for indoor, shore-based and shallow-water visible panoramic monitoring systems.
ZnS / ZnSe Infrared Crystal — High transmittance in MWIR and LWIR bands, essential for thermal imaging panoramic domes. ZnS offers better environmental durability; ZnSe provides lower absorption for high-sensitivity thermal cameras.
Fused Silica — Ultra-high transmittance from UV to near-IR with exceptional thermal shock stability. Ideal for near-infrared, laser and high-temperature panoramic dome applications.

Frequently Asked Questions
Q1: What is the difference between hyper dome and normal hemispherical dome?
A: Hyper hemispherical design achieves much wider panoramic field of view, effectively eliminate monitoring blind spots, while standard half-sphere dome has limited shooting range.
Q2: Can you provide optical simulation for my turret structure?
A: Yes, we offer free professional optical simulation according to your required FOV and camera parameters to optimize hyper dome radian design.
Q3: Is plastic hyper dome acceptable for industrial surveillance?
A: No, plastic will scratch, deform and degrade quickly in high altitude/marine environment; we only supply sapphire & infrared crystal optical domes for industrial OEM.
Q4: Can hyper dome match dual-band visible & thermal imaging system?
A: Sure, we support BBAR dual-band anti-reflection coating for simultaneous day monitoring and LWIR thermal detection.
Q5: Do you provide prototype hyper dome samples for testing?
A: We support small batch prototype samples for client panoramic imaging performance verification before mass order.
