Detailed

Custom BK7 Underwater Optical Glass Dome

Felix Glass specializes in manufacturing BK7 underwater optical glass domes for underwater cameras, ROV systems, deep-sea imaging equipment, and marine surveillance applications.

Our underwater optical domes are professionally engineered to deliver high-transmittance clear imaging, outstanding pressure resistance, and stable long-term waterproof sealing in both shallow and deep-sea harsh marine environments. Every dome supports full OEM customization including dimension size, spherical curvature, functional optical coating, and mounting edge interface to match customer camera housing structures.

Core Product Advantages

Ultra-high optical transmittance design to guarantee clear, distortion-free underwater imaging effect.

Reinforced pressure-resistant spherical structure, suitable for deep-sea high-pressure working conditions.

Precision machined edge finish, perfect matching with camera housing to realize reliable waterproof sealing.

Ultra-precision optical polishing technology to minimize image distortion during underwater shooting.

Multi-layer functional coating optional: anti-reflective AR coating, anti-fog coating and anti-scratch hard coating.

Complete OEM & ODM custom manufacturing service with prototype sampling support.

Custom Processing Options

1. Dimension Customization: Custom dome outer diameter, wall thickness and spherical curvature based on customer engineering drawings.

2. Pressure Structure Customization: Reinforced wall design for specified deep-sea pressure rating demands.

3. Substrate Material Customization: Standard N-BK7 optical glass; fused silica quartz alternative for high-performance deep sea scenarios.

4. Functional Coating Customization: Single/double side AR coating, anti-fog coating, scratch-resistant hard coating to eliminate fogging and surface abrasion.

5. Edge Finishing Customization: Precision chamfer polishing for stable waterproof sealing assembly.

6. Small Batch Support: Accept prototype orders with MOQ as low as 1 piece for early-stage equipment testing.

Typical Application Scenarios

This BK7 waterproof optical glass dome is the core optical protective component for all kinds of marine underwater equipment. It is widely equipped on consumer diving underwater cameras and industrial underwater imaging systems, ROV remotely operated vehicle optical detection systems, deep-sea exploration photography equipment, marine long-term surveillance monitoring devices, as well as underwater flaw inspection and optical detection instruments.

OEM Manufacturing Capability

Felix Glass supplies one-stop customized OEM & ODM processing service for underwater optical glass domes. Our complete production workflow includes optical glass blank cutting, ultra-precision spherical CNC polishing, multi-layer functional vacuum coating, precision edge finishing and strict optical & pressure compatibility performance testing.

We support small prototype sampling, medium trial batches and large-scale mass production. All underwater domes will go through full dimensional, appearance and optical transmittance inspection before delivery to meet deep-sea marine equipment standards.

Complete production technological flow: Glass Blank Cutting → Spherical CNC Precision Polishing → Functional AR/Anti-Fog Vacuum Coating → Optical Transmittance Test → Sealing Edge Finishing → Dust-Free Vacuum Protective Pack

FAQ

1. How to solve low clarity and image distortion underwater?

We adopt high-transmittance premium N-BK7 optical glass together with ultra-precision spherical polishing to reduce light refraction distortion and maintain high light transmittance for clear underwater imaging.

2. How to prevent water leakage under deep sea high pressure?

Our dome adopts reinforced pressure-resistant spherical structural design, plus precision chamfer edge finishing to achieve tight fit with camera housing and reliable long-term waterproof sealing.

3. How to avoid lens fogging and surface abrasion in marine environment?

We provide optional anti-fog coating and anti-scratch hard coating, which can effectively eliminate internal fogging and resist seawater corrosion & surface scratch damage for long service life.

4. Do you support prototype testing and mass bulk supply?

Prototype samples with MOQ 1 piece are available for equipment performance testing. We also support medium and large mass production batches, every finished dome will pass full optical inspection before shipment.
