Frequently Asked Questions About CVD ZnS Infrared Optical Domes
Can you manufacture custom CVD ZnS hemispherical dome windows per engineering drawings?
Yes. Felix Glass produces fully-custom CVD ZnS hemispherical infrared domes, custom outer diameter, wall thickness, curvature and edge-bevel strictly based on your engineering drawing.
What is the operating infrared band for CVD ZnS dome?
CVD-ZnS domes are optimized for long-wave infrared 8‑14 μm thermal imaging applications. Multi-spectral ZnS supports both visible + IR transmission.
What coating options are available for CVD ZnS infrared dome?
We provide vacuum-deposited IR anti-reflection coating tuned for 8‑14μm LWIR band. Uncoated domes are also available upon request.
CVD ZnS vs ZnSe vs Germanium dome: which one should I select?
Choose CVD ZnS for externally mounted protective domes for higher mechanical hardness and impact resistance. ZnSe delivers superior IR transmission but softer, recommended for internal low-stress optics. Germanium works well for indoor LWIR sensors.
Do you support prototype samples and OEM mass production?
Yes, single-piece prototype sampling is supported, and we can scale up to stable volume OEM orders for infrared-system projects.
What drawing formats do you accept for RFQ?
We accept PDF, DXF, DWG and STEP engineering drawing files for technical evaluation and formal RFQ quotation.
Can CVD ZnS dome withstand salt fog and marine environment?
CVD ZnS has excellent chemical stability. For offshore marine deployment, we can recommend optimized edge treatment and coating to resist salt spray and humidity.
