Diamond turning is ideal for making infrared optics because at longer wavelengths, optical performance is less sensitive to surface finish quality, and many LWIR optics materials are difficult to polish with traditional methods. Mostly, the diamond turning method does not need post-production polishing. Syntec Optics manufactures long-range IR optics using its high-precision SPDT processes. As a leading defense and medical optics supplier, Syntec Optics has gained expertise in designing, developing, and manufacturing high-precision LWIR optics. We can work with various materials for IR applications, including chalcogenide glass, zinc sulfide, Barium Fluoride, Cadmium Telluride, etc. Infrared lenses use specific substrates or anti-reflective coating to maximize performance. Our in-house optical coating facility ensures a quick turnaround time.
