Spherical sapphire dome is a curved hemispherical or dome-shaped piece made from synthetic sapphire, a highly durable and scratch-resistant material. Sapphire domes are commonly used in various high-performance applications due to their exceptional strength, hardness, optical clarity, and resistance to thermal and chemical damage.

The dome shape allows for broader viewing angles, making it ideal in situations where wide visibility is essential. It’s often used in high-tech applications like watchmaking, scientific instruments, aerospace, and medical devices. The dome shape allows for a wide field of view or a strong structural design, depending on the application.

The spherical dome’s shape offers additional mechanical strength, distributes stress more evenly, and minimizes refraction issues that could distort visibility at the edges. It makes creating optical lenses with broader field coverage and minimal distortion easier, particularly under challenging environmental conditions.

We have rich experience in manufacturing custom optical sapphire domes. We can produce a variety of custom sapphire domes, including sapphire hemispherical domes, sapphire hyper-hemispherical domes, kerfs sapphire domes, spherical sapphire domes, aspheric sapphire domes, sapphire domes (Sapphire fairing radome), U-shape sapphire domes, conformal sapphire domes, and special–shaped sapphire hyper-hemisphere dome.
The diameter of Blue Box optics custom sapphire domes can be manufactured up to Φ390mm.

Sapphire is a highly durable and scratch-resistant material, second in hardness only to diamond, which makes it ideal for harsh environments. The transparency and clarity of sapphire also make it excellent for optical applications, where high visibility and durability are crucial. The key uses of spherical sapphire domes are as below:

1. Optical Sensors and Cameras: Used as protective covers for sensors and lenses, especially in environments that are harsh or exposed to debris, extreme temperatures, or underwater.

2. Watches and Instruments: Sapphire domes serve as crystal covers on luxury watches, preventing scratches and ensuring long-lasting transparency, providing a scratch-resistant, clear view of the dial.

3. Aerospace and Defense: Protect sensors, cameras, and other sensitive equipment in aerospace, military, and underwater applications. Certain aerospace applications use sapphire domes for high-strength optical windows due to their ability to withstand high stress, temperature changes, and abrasive particles.

4. Scientific Equipment: Used in specialized microscopes and high-precision instruments due to their optical clarity and durability.

5. Optics and Cameras: In devices exposed to tough environments, such as underwater cameras, aerospace cameras, or industrial equipment, sapphire domes protect delicate optical components while maintaining clarity.

6. Scientific Instruments: Sapphire domes are used for pressure windows, particularly in extreme environments, like deep-sea submersibles or pressure chambers, where visibility and strength are essential.
