Custom Sapphire Optical Dome Manufacturer | ROV Military Aerospace Optic Window

 

Dongguan Felix Glass Co., Ltd. (Felix Glass) manufactures custom sapphire optical domes for underwater cameras, optical sensors and industrial imaging systems. We support drawing-based machining, precision polishing and optional optical coatings, from prototype evaluation to batch production.

 

Core Pain Point We Solve

 

Ordinary glass dome cracks under deepsea high pressure or scratch by seawater sediment, causing equipment failure & expensive downtime repair cost. Our single-crystal sapphire dome owns 9Mohs top hardness + IP68 full waterproof, enduring long-term deepsea & harsh military environment, cutting your equipment breakdown rate by 76%.

 

Core Spec

 

- Material: Single-crystal Sapphire / BK7 / Fused Silica

- Optional Coating: AR / IR Bandpass / Anti-fog AF Coating

- Shape: Custom Hemispherical / Spherical CNC Machining

- Thickness: 1.0-5.0mm Customizable | Hardness: 9 Mohs

- Application: Deepsea ROV, Military Night Surveillance, Aerospace Thermal Drone

 

✅ Exclusive Competitive Advantages

 

1. 9Mohs ultra-hard sapphire resists seawater scratch & high-pressure impact for deepsea ROV

2. IP68 waterproof sealed structure fits all harsh deep-water working conditions

3. Custom AR/IR coating improves transmittance for thermal drone imaging & military monitoring

4. In-house CNC precision machining meets strict aerospace equipment tolerance standard

5. Alternative BK7/fused silica material lowers cost for regular industrial aerospace projects

 

QC & Production Lead Time

 

ISO9001 certified full inspection for each dome; sample lead time 3-5 days, bulk order 10-15 days.

MOQ 5pcs trial order available for lab & prototype test.

 

Global Cooperation Policy

 

Custom pricing is based on your drawings, material, dimensions, tolerances, coating requirements and order quantity. We aim to respond within one business day. Formal quotations are typically provided within 1–2 business days after complete specifications are received. Complex projects may require additional engineering review, and we will advise you of the expected quotation timeline.
