Large Custom Sapphire Optical Dome for Oversize Sensor Protection
Felix Glass Co., Limited manufactures large custom sapphire optical domes for camera housings, ROV systems, thermal imaging assemblies, drone payloads, aerospace equipment and medical or industrial optical devices that require a hard spherical protective cover.
synthetic single-crystal sapphire, optional BK7 or K9 optical glass discussion, AR / IR / UV / AF coating options, custom diameter, Mohs 9 hardness, high transmittance, pressure resistance, waterproof performance, low distortion and OEM project support.
Direct answer
What This Oversize Sapphire Spherical Cover Is Built For
A large sapphire optical dome is used when the optical path needs a rounded protective window instead of a flat cover. The dome form supports wide viewing angles, sealed housings and compact optical assemblies while sapphire helps resist scratches, weather exposure and repeated cleaning.
Optical Review by Band
Visible, IR, UV and coating requirements can be reviewed against the final sensor or imaging system.
Drawing-Based Customization
Diameter, radius, wall thickness, edge geometry and coating stack can be matched to customer drawings.

Material, Size and Coating Options Kept from the Original Listing
The primary material is synthetic single-crystal sapphire. BK7 or K9 optical glass can be discussed as a secondary custom option when the application needs optical clarity but does not require sapphire hardness.
- Material: synthetic single-crystal sapphire, with BK7/K9 optical glass as optional alternatives.
- Diameter reference: 5 mm to 300 mm customizable for this listed configuration.
- Shape: hemispherical, spherical or half-sphere dome according to assembly design.
- Coatings: AR, IR, UV and AF coating options can be specified by use environment.

Application Fit for Market Engineering Teams
buyers often compare sapphire optical components by service environment, sensor wavelength, pressure exposure and replacement cost. These use cases help define whether sapphire, BK7 or K9 is the right route.
Underwater ROV and Marine Cameras
Use sapphire when the dome may face pressure, saltwater exposure, abrasion and frequent cleaning.
Thermal Imaging and Aerospace Systems
Coating, wavelength range, wall thickness and distortion control should be reviewed together.
Surveillance and Industrial Vision
For exposed optical systems, sapphire can reduce surface damage caused by dust, handling and weather.

How the Dome Design Is Reviewed Before Production
A reliable sapphire dome quotation starts with the drawing and working conditions. Felix Glass checks the dome radius, diameter, wall thickness, mounting edge, coating requirement, optical zone and inspection standard before confirming production feasibility.
Production logic
Custom Manufacturing Flow for Large Sapphire Optical Domes
The exact process changes with geometry and coating, but the evaluation path is consistent from prototype discussion to repeat production.
Drawing Review
Confirm diameter, curvature, wall thickness, edge form, optical zone and mounting method.
Material Selection
Select sapphire, BK7 or K9 according to hardness, transmission band, budget and environment.
Forming and Polishing
Process the dome surface to support optical clarity and low-distortion viewing.
Coating Review
Define AR, IR, UV or AF coating targets by wavelength, reflection control and cleaning exposure.
Inspection and Packing
Check dimensions, appearance, coating surface and packing protection before shipment.
Decision support
When Sapphire Is the Better Choice Than BK7 or K9 Optical Glass
The original listing includes both sapphire and optical glass options. The right choice should be based on working environment rather than material name alone.
Choose Sapphire
For abrasion, outdoor service, marine exposure, pressure risk, frequent cleaning, high durability needs or longer replacement cycles.
Review BK7 or K9
For indoor visible-light systems where cost, optical clarity and uniformity matter more than maximum hardness.
Confirm Coating Early
AR, IR, UV and AF coatings should be planned before final quote because coating affects optical performance and lead time.
Trust signals
Inspection Points That Matter for Oversize Spherical Covers
Large domes are sensitive to geometry, appearance and installation details. Practical inspection may include dimensional checks, surface appearance review, coating appearance, optical clarity, waterproof or pressure-related requirements and packaging protection.

FAQ for Large Custom Sapphire Optical Dome Projects
Can you produce a large sapphire optical dome?
Yes. This listing supports custom sapphire dome work, with a listed diameter reference from 5 mm to 300 mm. Send the drawing for a geometry check.
What is the difference between sapphire and BK7 dome material?
Sapphire is selected for hardness, scratch resistance and harsh environments. BK7 or K9 may be suitable for visible-light projects that do not need sapphire durability.
Can the dome be waterproof and pressure resistant?
The original listing supports waterproof and pressure-resistant project requirements. Final capability depends on wall thickness, edge design, sealing structure and test conditions.
Can AR, IR, UV or AF coating be customized?
Yes. Coating should be matched to wavelength range, reflection target, cleaning method and the final equipment environment.
What should be sent for a quotation?
Please send diameter, radius, wall thickness, edge drawing, material choice, coating request, quantity, application and inspection requirements.
