Product Description

Our silicon plano convex lenses are manufactured from high-purity Si material, optimized for infrared applications between 1.2–8.0 μm. Designed with a convex and a flat surface, they offer a positive focal length that is well-suited for beam collimation, focusing point sources, and reducing focal length in optical systems. With an IR AR coating in the 3–5 μm range, these lenses achieve high transmission efficiency and durability. Their excellent thermal conductivity ensures stable performance under high-power laser or infrared environments. Silicon plano convex lenses are widely used in infrared imaging, thermal imaging cameras, terahertz systems, medical instruments, and military optics.
