Metals, ceramics & composites planar lenses are advanced flat optics for compact optical designs. Unlike curved lenses, their flat surfaces eliminate spherical aberration and simplify assembly, ideal for ultra‑thin imagers, portable spectrometers, laser rangefinders and aerospace optoelectronics.
Fabricated by ultra‑precision grinding, polishing and coating with strict quality control, they feature low surface roughness and stable optical performance. Each material brings unique advantages: metals for high‑power laser heat dissipation, ceramics for high‑hardness harsh‑environment use, and lightweight composites for aerospace and portable devices.
