Customization & Service Support
Beyond our standard stock catalog, we offer full customization services for ZnSe plano-convex lenses to fit your specific system requirements. Options include custom diameters, focal lengths, and surface profiles, as well as a range of infrared coatings such as BBAR and DLC for enhanced performance and durability. Every custom part undergoes a full engineering drawing review before quotation to ensure design feasibility and performance alignment with your operating conditions.
All our CO2 laser optics are manufactured under ISO 9001:2015 compliant processes, with strict inspection protocols for surface quality, dimensional accuracy, and optical performance. We maintain reliable lead times for both stock and custom orders, with dedicated engineering support to assist with material selection, coating recommendation, and design optimization.
Get Your Optical Solution Started
Sourcing precision infrared optics often comes with common challenges: extended lead times for custom parts, limited engineering support during the design phase, and difficulty matching exact tolerance and performance requirements. At iroptical, we address these pain points with our extensive in-stock inventory, responsive engineering team, and proven manufacturing track record for high-precision ZnSe components.
If you need a custom configuration, have questions about coating options, or want to verify compatibility with your system, send your drawing and requirements to sales@iroptical.com, or use our online RFQ form to request a detailed quotation with confirmed lead time information.
