Shanghai Optics specializes in the custom manufacturing of high-quality Zinc Selenide (ZnSe) lenses, which are ideal for mid-infrared applications like thermal imaging and high-power CO2 laser systems due to 0.5-21µm transmission range and low absorption at 10.6 μm. These lenses, made from chemically vapor deposited ZnSe blanks, offer high resistance to thermal shock and can be custom-designed in various forms (spherical, cylindrical, meniscus, aspherical, etc.) with optional AR coatings.

Shanghai Optics specializes in precision manufacturing using diamond turning and rigorous testing to meet specific requirements, leveraging our 55 years of experience to deliver competitive pricing and expert consultation.
