We support both prototype small‑batch and mass‑production orders for sapphire domes. MOQ varies based on diameter, wall thickness and coating requirements. Contact us with your drawing for exact MOQ details.
Maximum Diameter
Our available sapphire dome maximum diameter covers common ROV, LiDAR and optical sensor application ranges. Send us your dimension requirements to check manufacturability.
Sapphire Crystal Orientation
C‑plane, A‑plane and R‑plane orientations are available for sapphire domes. Crystal orientation directly impacts mechanical strength and optical performance, please specify in your drawing.
Wall Thickness
Wall thickness is critical for pressure‑resistant sapphire domes. We can fabricate custom wall thickness according to your underwater pressure and structural simulation data.
Concentricity
Tight concentricity tolerance is maintained for sapphire domes to avoid optical distortion. Tolerance values can be customized per your optical system specification.
Surface Quality
We deliver different surface quality grades for sapphire domes, meeting MIL‑PRF‑13830 or ISO 10110 standards for scratch‑dig requirements.
AR Coating
Multi‑layer AR anti‑reflection coatings can be applied on single‑side or double‑side for target wavelength bands, optimizing transmittance for your optical system.
Underwater Pressure
Our sapphire domes are widely used for underwater ROV/AUV applications. Pressure resistance depends on diameter, wall thickness and crystal orientation, share your depth requirement for engineering review.
High Temperature
Sapphire features excellent high‑temperature resistance. We can provide engineering evaluation for high‑temperature working‑condition sapphire dome projects.
Prototype Lead Time
Prototype lead‑time depends on dome size, tolerance and coating complexity. General prototype turnaround will be advised after receiving your technical drawings.
Inspection Report
Full‑set inspection reports including dimension measurement, surface quality report and coating test data can be provided together with shipments.
Drawing Requirements
Please provide 2D/3D drawings with dimension, tolerance, surface quality, coating and working‑condition requirements for accurate quotation and engineering assessment.
