sapphire hemispherical optical dome for aerospace missile EO/IR thermal imaging system

MWIR / LWIR Thermal Imaging IR Dome

Custom ZnS / ZnSe / Sapphire Infrared Optical Domes for Thermal Surveillance & EOIR Turrets

Felix Glass manufactures A-grade MWIR and LWIR thermal imaging IR domes tailored for professional infrared detection and day-night dual-band surveillance systems. Different from ordinary visible-light optical domes, our infrared domes adopt exclusive IR-transparent materials and targeted spectral coating technology, ensuring ultra-high transmittance in mid-wave and long-wave infrared bands. Ideal for aerospace UAV turrets, industrial thermal monitoring and infrared imaging equipment, delivering stable and clear thermal imaging performance in low-light and full-dark environments.

Core Pain Points We Solve

Ordinary glass domes block infrared spectrum, resulting in invalid thermal imaging and low detection accuracy

Untargeted coating causes low MWIR/LWIR transmittance, blurring night thermal surveillance footage

Generic optical domes suffer thermal shock and abrasion in high-frequency thermal detection scenarios

Most suppliers cannot customize precise spectral coatings for exclusive infrared wavelength bands

Product Key Advantages

Professional IR Transparent Material System

Exclusive selection of infrared-specific materials including ZnS, ZnSe and infrared-grade sapphire. Perfectly adapt to MWIR (3–5μm) and LWIR (8–14μm) working bands, solving the fundamental problem that ordinary optical glass cannot transmit infrared light.

Custom MWIR/LWIR Targeted AR Coating

Support customized single-band and dual-band infrared anti-reflection coatings. Greatly improves infrared spectral transmittance, suppresses stray light and background interference, and delivers clearer thermal imaging contrast for night surveillance.

Ultra-Low Distortion Infrared Polishing

Adopts aerospace-grade ultra-precision surface processing technology. Strict optical uniformity and flatness control ensure zero distortion thermal imaging output, meeting high-precision infrared detection and tracking requirements.

Excellent Thermal & Mechanical Stability

IR dome materials feature stable physical properties, strong thermal shock resistance and low thermal expansion rate. Maintain consistent optical performance during long-term high-frequency infrared detection and temperature changes.

Dual-Band Day & Night Surveillance Compatible

Matches EOIR dual-spectrum turret systems, supporting synchronous visible light monitoring and infrared thermal imaging. One dome meets all-weather day and night surveillance operational needs.

Pure Infrared Vertical Customization

Focus on infrared optical dome R&D and production, independent from visible-light dome process. Provide exclusive optical solutions for thermal imaging equipment manufacturers.

Frequently Asked Questions

Q1: What is the difference between IR dome and ordinary optical dome?

A: Ordinary glass cannot transmit mid-wave and long-wave infrared light. Our IR domes adopt professional infrared materials and targeted coatings, specially designed for thermal imaging and infrared detection systems.

Q2: Can you customize coating for specific infrared wavelength?

A: Yes. We support exclusive AR coating customization for 3–5μm MWIR and 8–14μm LWIR, and can develop special spectral solutions according to your camera chip parameters.

Q3: Which material should I choose, ZnS, ZnSe or sapphire?

A: ZnS is cost-effective for conventional thermal imaging; ZnSe has higher transmittance for high-end LWIR equipment; infrared sapphire is more suitable for scenarios requiring high hardness and impact resistance.

Q4: Do you support custom diameter and thickness?

A: Fully customizable. We provide OEM processing according to your turret installation size, structural tolerance and optical design requirements.

Q5: Can you provide prototype samples for testing?

A: Yes. We support small-batch sample customization for client performance verification before mass production.
