Product description
Optical glass spherical lenses are foundational imaging and beam-shaping elements across visible and near-infrared systems. Sichuan Yuchuang Infrared Optics manufactures plano-convex, bi-convex, plano-concave, and meniscus designs for OEM instruments, laser platforms, and research assemblies.
Substrates include N-BK7 / K9 and fused silica. Typical working band covers approximately 350–2500 nm depending on material and coating. Diameter capability spans 1–500 mm, with surface figure down to λ/10 and scratch-dig from commercial 60/40 to research-grade 10-5.
AR, HR, and custom dielectric coatings are available. Each lot can be verified with interferometry and dimensional metrology before shipment, supporting both prototype and volume programs.
