Direct answer

What This Mohs 9 Sapphire Cover Is Designed to Solve

A sapphire optical dome is selected when a flat window or standard glass cover does not provide enough scratch resistance, pressure durability, heat stability or optical protection. The dome shape helps protect the optical path while supporting wide-angle viewing or compact sensor enclosure designs.

Mohs 9 Surface

Single crystal sapphire helps resist abrasion from sand, cleaning, handling and outdoor service conditions.

Clear Optical Path

Polishing and optional AR coating are matched to the required visible, NIR or selected IR use case.

Drawing-Based Build

Diameter, radius, wall thickness, edge detail, coating and inspection criteria can be reviewed before production.

Attention to specification

Material and Coating Details for Engineering Review

The standard material is synthetic single-crystal sapphire, also known as Al2O3 corundum. BK7 or K9 optical glass can be discussed as a secondary custom option when the project does not require sapphire hardness.

Material: Synthetic single crystal sapphire for hard optical protection.
Hardness: Mohs 9 surface hardness for scratch and wear resistance.
Coating: AR anti-reflective, AF anti-fingerprint and AG anti-glare options can be reviewed.
Service: OEM and ODM customization for small batch sampling or repeat production.

Where AR Coated Sapphire Domes Are Commonly Used

Use conditions should define the final dome size, coating and inspection standard. The same material family can serve different environments when the geometry and coating are specified correctly.

Sapphire optical dome for underwater ROV camera protection

ROV and Marine Cameras

For subsea imaging, pressure, corrosion, sealing and optical clarity must be considered together.

Sapphire dome cover for aerospace and industrial optical sensor protection

Aerospace and EO/IR Sensors

For airborne or defense-related equipment, drawings often define material, coating and inspection requirements.

Scratch resistant sapphire protective cover for industrial optical equipment

Industrial Vision Equipment

For inspection cameras and monitoring systems, sapphire helps protect exposed optics from abrasion and cleaning.

How Felix Glass Reviews a Sapphire Optical Dome RFQ

Drawing Review

Diameter, radius, wall thickness, flange or edge form, optical zone and mounting method are checked.

Material Planning

Sapphire blank size, machining allowance and coating route are planned according to the application.

Grinding and Polishing

Diamond tooling and controlled polishing are used to form the dome and improve optical clarity.

Coating Review

AR, AF, AG or other coatings are selected by wavelength range, cleaning method and service environment.

Inspection and Packing

Finished parts are checked for dimensions, surface quality, coating appearance and shipment protection.

Original capability retained

Custom Options from Prototype Sampling to Batch Orders

The original listing supports small custom orders and larger-volume production. For a practical quotation, send your dome drawing, target quantity, material requirement, coating request, tolerance, surface quality, working environment and any inspection standard.

Sample timing and bulk delivery depend on geometry, coating and inspection requirements. For simple projects, Felix Glass can review feasibility quickly; for complex optical assemblies, engineering discussion helps avoid overbuilding the part.

Decision support

When to Choose Sapphire Instead of Standard Optical Glass

Choose Sapphire When

The cover faces abrasion, repeated cleaning, salt fog, heat, pressure, outdoor exposure or long-service optical protection requirements.

Review BK7 or K9 When

The part needs optical clarity but does not require sapphire hardness or severe environment resistance.

Confirm Coating When

The optical system has a defined wavelength band, reflection target, fingerprint exposure or glare concern.

Buyer FAQ

Questions Before Ordering a Mohs 9 Sapphire Optical Dome

Can the dome diameter and radius be customized?

Yes. The part can be reviewed by drawing for diameter, spherical radius, wall thickness, edge detail and optical zone.

Does AR coating always reach the same transmittance?

No. Transmission depends on wavelength range, coating design, material thickness and inspection method. Share the optical band for review.

Is sapphire suitable for underwater ROV cameras?

Sapphire is often selected for underwater optical covers because it offers hardness, corrosion resistance and stable optical protection when the housing design is correct.

What information helps speed up a quotation?

Please provide drawing, material, size, radius, thickness, coating, quantity, application environment and inspection requirements.
