AR Coated Optical Glass Dome: Quality & Transmittance Guide
Optical glass domes are essential protective components for surveillance cameras, underwater sensors, industrial monitoring systems and optical instruments. Their performance, image clarity and service life are directly determined by two core factors: **anti-reflective (AR) coating quality** and **precision manufacturing & quality control**.
## Why AR Coating Is Critical for Optical Glass Domes
Uncoated optical glass domes reflect 8-10% of light on each surface, causing glare, reduced transmittance and blurred images. High-quality multi-layer AR coating solves this problem by:
- Boosting light transmittance to over 98% across the visible spectrum
- Eliminating unwanted reflections for clearer camera/sensor performance
- Adding scratch-resistant and anti-fingerprint properties for outdoor use
- Maintaining consistent performance in extreme temperatures and humidity
At Felix Glass, our AR coated optical domes undergo strict testing to ensure uniform coating thickness, high adhesion and long-term durability, even in harsh industrial and underwater environments.
## Our 5-Step Quality Control for Optical Glass Domes
As a trusted optical glass supplier, we implement rigorous quality checks on every dome we produce:
1. **Raw Material Selection**: We use premium BK7 and K9 optical glass for stable optical properties.
2. **Precision Polishing**: Domes are polished to 60/40 surface quality with tight dimensional tolerances.
3. **AR Coating & Testing**: Each dome is coated with multi-layer AR films and tested for transmittance and reflectance.
4. **Environmental & Durability Tests**: Products undergo temperature cycling, humidity and vibration tests.
5. **Final Visual & Metrology Inspection**: All domes are checked for defects before packaging and shipment.
