Sapphire Dome and Double Dome
The critical distinction for sapphire dome and double dome is the combination of material grade, geometry and post-processing condition, all of which should be reflected in the specification sheet. Contact WEGITEK with your required specifications, quantity and drawings for a technical quotation.
Sapphire Dome and Double Dome: Material Overview
Sapphire Dome and Double Dome is considered for optical protection, semiconductor processing, crystal research, sensing, photonics and precision mechanical assemblies. Sapphire combines high hardness, chemical stability and broad optical usefulness with controlled single-crystal orientation. Final performance depends on geometry, surface state and mounting conditions. Curved sapphire optics require control of curvature, clear aperture, center/edge thickness and polishing.

Engineering and Specification Considerations
Specify dome geometry with a drawing and confirm coating and optical inspection.
- C/A/R/M orientation
- diameter or drawing
- thickness
- SSP/DSP
- optical surface quality
- chamfers
- coating and inspection method
Quality and Inspection Priorities
Engineering acceptance should be defined before order confirmation. Depending on grade and use, the inspection review may include:
- Crystal orientation
- inclusions
- surface scratches/digs
- roughness
- flatness
- thickness variation
- edge finish and optical transmission where relevant
Where possible, request the inspection method, measurement location and batch documentation alongside the numeric limit.
Applications and Selection Guidance
Potential application fields include optical protection, semiconductor processing, crystal research, sensing, photonics and precision mechanical assemblies. The final selection depends on thermal, electrical, optical and mechanical operating conditions. Share the process step and acceptance criteria to help the supplier evaluate feasibility.
Frequently Asked Question
Does sapphire orientation matter for a custom component?
Yes. The requested crystal plane and cut direction can affect processing, optical response, mechanical behavior and downstream fabrication. Confirm orientation with the end-use drawing.
What should be included in a request for quotation?
Send the part name or drawing, material grade, diameter/size, thickness, orientation, surface finish, quantity and required tests. If you have a target delivery date or acceptance specification, include it at the outset.
