Custom Marine-Grade Single Crystal Sapphire Optical Window | Saltwater Resistant, Deep-Sea Extreme Pressure Tolerance Share your subsea optical parameters and drawings. Our optical engineers provide free technical evaluation. Felix Glass supplies custom subsea sapphire viewports to North American marine robotics manufacturers for ROV underwater inspection cameras. Our sapphire windows successfully passed continuous salt fog and high-pressure cycling tests, significantly extending the service life of subsea imaging equipment. Q1: Can you supply samples for equipment verification testing? A: Yes. We provide prototype samples for performance validation prior to bulk orders. Q2: Can sapphire viewports be customized in dimensions and shapes? A: Fully customizable. Send your engineering drawings for professional technical evaluation. Q3: Are pressure resistance and optical test reports available? A: Formal inspection documentation can be provided upon customer request with each shipment. Q4: What coating solutions are recommended for marine sapphire windows? A: Broadband anti-reflection (AR) coating is the standard choice for underwater imaging camera systems. Q5: What is the lead time for prototypes and mass orders? A: Sample turnaround depends on machining complexity. We confirm exact schedules after drawing review. Share your technical requirements, CAD drawings and target specifications. Our optical engineers will respond within 24 working hours.
