Sapphire Optical Dome – High-Precision Optical Protection
Product Overview
The Sapphire Optical Dome is a premium-grade optical protection
component designed to meet the most demanding requirements in
high-performance imaging and sensor applications. Fabricated from
synthetic single-crystal sapphire (Al₂O₃), the sapphire optical
dome combines outstanding optical clarity, exceptional durability,
and thermal stability within a single component. Unlike
conventional glass or polymer domes, the sapphire optical dome
maintains excellent transmission across ultraviolet (UV), visible,
and infrared (IR) spectra, making it indispensable for systems
operating in extreme environments such as aerospace, marine
exploration, and industrial laser systems.
Key Features and Advantages
Wide Spectral Transmission: High optical transmittance from 200 nm
to 5000 nm, covering UV, visible, and IR ranges for versatile
applications.
Superior Hardness and Scratch Resistance: With a Mohs hardness of
9, the sapphire optical dome is highly resistant to surface damage,
ensuring consistent optical performance over time.
Thermal Resistance: Operates reliably in continuous
high-temperature environments up to 1000°C, supporting use in
aerospace and industrial laser applications.
Pressure and Impact Resistance: Exceptional mechanical strength
allows the sapphire dome to withstand high-pressure underwater
environments and dynamic mechanical stress.
Chemical Durability: Resistant to seawater, strong acids, alkalis,
and other corrosive substances, ensuring stable performance in
challenging conditions.
Applications
Aerospace and Defense: IR optical domes for missile seekers,
airborne sensors, and targeting systems.
Marine Exploration: Protective domes for ROVs (Remotely Operated
Vehicles), underwater cameras, and sonar optical sensors.
Industrial and Scientific Research: Laser systems, spectroscopy
equipment, and high-speed imaging devices requiring durable optical
windows.
Why Choose Our Sapphire Optical Dome?
We employ state-of-the-art crystal growth, precision CNC machining,
and optical polishing to manufacture sapphire domes with superior
surface accuracy (λ/10 flatness) and low birefringence, ensuring
unmatched optical performance. Optional anti-reflective (AR),
diamond-like carbon (DLC), or hydrophobic coatings can be applied
for enhanced functionality.
FAQ
What makes a sapphire optical dome superior to a glass dome?
Sapphire offers much higher hardness, scratch resistance, and
temperature stability, making it ideal for harsh environments where
glass would fail.
Can you provide custom sizes and coatings?
Yes, we offer custom diameters, thicknesses, and coatings to match
specific optical and environmental requirements.
Is the sapphire optical dome suitable for deep-sea use?
Absolutely. Its high compressive strength and corrosion resistance
make it an excellent choice for underwater imaging.
What is the lead time for custom sapphire domes?
Lead times vary by specification, but we typically deliver within
3–6 weeks for custom orders.
