How much do you know about ZnS plano concave lens?

With the rapid development of military weaponry and correlative targeting and monitoring systems, ZnS plano concave lens is widely utilized in multi-spectral IR applications. Its relatively high transmittance through 3-5μm and 8-10μm enable ZnS being an ideal choice for multi-spectral applications. Further, within NIR and SWIR range, CLEARTRAN CVD ZnS can also be considered as indispensable alternative for optical designers.

Tiancheng Optics uses CLEARTRAN ZnS multi-spectral material from ROHM&HAAS, typical material arrival lead time is 2 weeks. CLEARTRAN ZnS is modified by post-deposition hot isostatic process from CVD Zinc Sulfide, which contributes to transmittance from visible till far infrared ranges (0.35 to 14μm). Therefore, ZnS cylindrical lens has become an imperative choice for IR lenses, laser windows and thermal imaging applications.
