Detail Information
Custom infrared-transparent sapphire dome lens
AR Coated Sapphire Hemispherical Lens for Protected Optical Systems
Hong Kong Felix Glass Co., Limited manufactures custom sapphire hemispherical lens and optical dome components for cameras, sensors, laser systems, underwater equipment, aerospace devices and industrial optical assemblies that need a hard, clear protective optical cover.
This renovation keeps the original product direction: sapphire, BK7, fused silica and K9 options; AR, IR, UV and AF coating choices; custom 5 mm to 200 mm diameters; OEM support; and practical engineering review before production.
Direct answer
What This Sapphire Optical Dome Lens Helps Protect
A sapphire hemispherical lens is used when the optical path must stay protected from abrasion, pressure, cleaning wear, outdoor exposure or harsh service conditions while maintaining useful transmission for camera, sensor or optical instrument work.
Compared with a flat cover window, the hemispherical form can support wider viewing geometry and compact sealed housings. Compared with ordinary glass, sapphire provides Mohs 9 hardness for projects where surface durability matters.
Coated Transmission
AR, IR, UV or AF coating can be discussed according to the target wavelength band and operating environment.
Custom Geometry
Diameter, radius, wall thickness, edge detail and inspection criteria are reviewed from the drawing.
Attention stage
Material Options for Sapphire, BK7, Fused Silica and K9 Designs
The original listing supports multiple optical materials. Sapphire is selected for high hardness and environmental stability, while BK7, fused silica or K9 can be reviewed when cost, optical band or project requirements point to another material.
- Sapphire: Mohs 9 hardness for scratch-resistant optical dome and lens covers.
- BK7/K9: Useful for precision optical designs that do not require sapphire hardness.
- Fused silica: Considered when the optical band or thermal behavior requires it.
- Custom review: Material selection should match wavelength, environment, housing design and quantity.

Application fit
Applications for Infrared Transparent Sapphire Optical Dome Lenses
The same dome concept can serve different optical systems when the drawing, material and coating are matched to the working environment. Felix Glass reviews each project around the actual use case instead of treating the lens as a standard catalog part.
Surveillance and Security Cameras
For outdoor cameras, exposed optics may need a hard dome cover with coating selected for reflection control and clarity.
Underwater ROV Equipment
Marine housings require careful review of pressure, sealing, corrosion exposure and viewing geometry.
Laser, Medical, Aerospace and Drones
Specialized systems often need defined material, coating, surface quality and inspection requirements.
Optical coating
How AR, IR, UV and AF Coatings Are Selected
Coating selection should start with the wavelength band, required reflection control, cleaning exposure, operating temperature and inspection method. A general AR coating may be enough for a camera dome, while an infrared optical system may need a more specific coating target.
AR Coating
Reduces reflection and supports higher useful transmission in the specified optical band.
IR or UV Review
Matches the material and coating stack to infrared or ultraviolet optical requirements when applicable.
AF Surface Option
Can be discussed for lens covers that need easier cleaning or reduced fingerprint marking.

Drawing-Based Manufacturing Review Before Quotation
Application Check
Confirm camera, sensor, laser, medical, aerospace, drone or underwater use conditions.
Drawing Review
Review diameter, spherical radius, wall thickness, edge treatment, mounting area and tolerance.
Material Decision
Select sapphire, BK7, fused silica or K9 according to the optical and mechanical priorities.
Coating Planning
Define AR, IR, UV or AF coating details based on wavelength and operating environment.
Inspection Scope
Set practical checks for dimensions, surface quality, optical appearance and coating condition.
Quality control
Inspection Points for Low Distortion and Stable Optical Performance
Each custom optical dome lens should be checked against the agreed drawing and order requirements. Typical review points include dimensions, visual surface quality, coating appearance, optical clarity, edge finish and packaging protection.
For US-market buyers, this approach helps purchasing and engineering teams compare suppliers by specification fit, not only by a short product title.
Decision support
When to Choose Sapphire for a Hemispherical Optical Cover
Choose Sapphire When
The optical cover faces abrasion, cleaning cycles, outdoor exposure, pressure, heat or long-service durability concerns.
Review BK7 or K9 When
The project needs precision optical glass but the environment does not justify sapphire hardness.
Review Fused Silica When
The wavelength band, thermal behavior or system specification points beyond standard optical glass.

Buyer FAQ
Questions Before Ordering a Custom Sapphire Hemispherical Lens
Can the diameter be customized from 5 mm to 200 mm?
Yes. The final feasible size depends on material, dome radius, wall thickness, edge design, tolerance and quantity.
Is sapphire always the right material?
No. Sapphire is suitable when hardness and environmental resistance matter. BK7, fused silica or K9 may fit other optical priorities.
What coating information should be provided?
Share the target wavelength band, expected reflection requirement, environment, cleaning method and any inspection standard.
What helps speed up quotation?
Send a drawing, material preference, diameter, radius, thickness, coating, quantity, application and tolerance requirements.
