Optical Sapphire Glass Dome Lens for Underwater Photography

Optical sapphire glass dome lenses are revolutionizing underwater photography and exploration. These domes, composed of two parallel optical surfaces, are unique in their ability to have no optical effect, making them ideal for capturing split-level images above and below water. Made from durable materials like sapphire, these lenses are designed to withstand harsh environmental conditions, including wind, rain, and deep-sea pressure, ensuring long-lasting performance.

Key Features and Specifications

Our optical sapphire glass dome lenses are engineered with precision to meet the demands of professional photographers and explorers:

• Material Options: Available in BK7, fused silica, and sapphire, each offering unique benefits such as scratch resistance and optical clarity.
• Surface Flatness: λ/2 ensures minimal distortion for sharp and clear images.
• Diameter: 50mm with a tight tolerance of ±0.05mm for consistent quality.
• Thickness Tolerance: ±0.05mm guarantees uniformity and durability.
• Surface Quality: 60/40 standard ensures minimal imperfections and high-quality imaging.
• Clear Aperture: 90% provides a wide field of view for stunning underwater shots.

Advantages of Using Dome Ports for Underwater Photography

Dome ports offer several advantages that make them indispensable for underwater photography:

• Aberration Correction: Domes correct light refraction issues caused by water, delivering sharper and more vibrant images compared to flat ports.
• Improved Split-Level Shots: The curved design allows seamless transitions between underwater and above-water scenes, creating stunning split-level compositions.
• Better Corner Sharpness: Larger domes enhance image quality at the edges and corners, making them ideal for wide-angle shots.
• Water Shedding: Glass domes, especially those made of sapphire, shed water more effectively, reducing unwanted reflections during split-level photography.
• Versatility: Suitable for both professional photographers and hobbyists, dome ports allow creative freedom without requiring advanced skills.

Glass vs. Acrylic Dome Ports: Which is Better?

Choosing between glass and acrylic dome ports depends on your specific needs and budget:

• Image Quality: Both materials perform well underwater, but glass handles flares and direct sunlight better, making it ideal for wide-angle shots.
• Price: Acrylic domes are more affordable, often costing half as much as glass domes of similar size.
• Durability: Glass is harder to scratch or damage, while minor scratches on acrylic domes can be repaired with polishing kits.
• Depth Ratings: Acrylic domes typically have higher depth ratings (up to 150m) compared to glass domes (up to 100m).
• Buoyancy and Balance: Glass domes provide better balance underwater, while acrylic domes may tilt due to buoyancy.

The Importance of Dome Size

The size of the dome port plays a critical role in image quality and usability:

• Corner Sharpness: Larger domes improve sharpness at the edges and corners, making them ideal for rectilinear lenses.
• Sensor Compatibility: Smaller sensor cameras benefit from smaller domes, which retain good image quality while being more portable.
• Fisheye Lenses: Smaller domes are preferred for fisheye lenses, allowing closer focus and easier use in tight spaces.
• Split-Level Photography: Larger domes create thinner meniscus lines, enhancing split-level shots.

Applications of Optical Sapphire Glass Dome Lenses

These lenses are widely used in various fields, including:

• Underwater Photography: Ideal for capturing vibrant marine life and split-level images.
• Deep-Sea Exploration: Used in submersible vehicles for oceanic research and defense applications.
• Action Cameras: Compatible with GoPro and other action cameras, enabling stunning over/under shots with ease.
