🛠️ Advanced Materials and Processes

We work with a wide range of optical materials including:

• Optical glass (N-BK7, Fused Silica, CaF₂, MgF₂, S-TIH6, etc.)

• Infrared materials (Ge, ZnSe, ZnS, AMTIR, Chalcogenide glass)

• Optical plastics (PMMA, PC, COP, OKP-1, MR-series, ZEONEX, APEL, TOPAS, E48R)

• Coating options: AR, HR, beamsplitter, ITO, dielectric, metal, bandpass, longpass, etc.

All optics are manufactured in-house using diamond turning, CNC-generated blanks, ultra-precision grinding & polishing, and cleanroom-level assembly when needed. Every component passes rigorous metrology using Zygo interferometers, profilometers, and MTF test benches.
