Customization & Service
Beyond standard stock units, we provide full customization services aligned with your project drawings and performance requirements. Available modifications include custom anti-reflection coatings, alternative dimensions, adjusted tolerance grades, and bespoke optical geometries. Every custom order receives a formal engineering drawing review before quotation to ensure manufacturability and performance alignment.
All ZnSe optics from iroptical are produced under ISO 9001:2015 certified workflows, with multi-stage inspection covering surface quality, dimensional accuracy, and optical performance. We maintain controlled, reliable lead times for both stock and custom orders, with dedicated technical support available from initial inquiry through post-delivery integration.
Sourcing Support & Inquiry
We recognize the core challenges engineering and sourcing teams face when procuring precision infrared optics: unpredictable lead times delaying project milestones, limited technical guidance for custom designs, and inconsistent quality across production batches. At iroptical, we address these pain points with ready-to-ship in-stock inventory, pre-quote engineering reviews, and batch-to-batch consistency backed by order-specific inspection records.
For volume inquiries, custom configuration requests, or technical questions, reach out to our optical specialists at sales@iroptical.com to receive a tailored quotation and engineering consultation.
