特注サファイア光学ウィンドウ レーザー＆航空宇宙用高硬度光学ガラス

製品概要

Sapphire custom-shaped optical windows are premium optical components made from 99.999% pure single-crystal sapphire (Al₂O₃). Renowned for their extraordinary hardness (Mohs 9) and superior optical clarity, these windows are engineered to meet the most demanding requirements in aerospace, laser systems, defense, and industrial applications. Compared to conventional optical glass, sapphire optical windows offer superior scratch resistance, exceptional thermal stability, and excellent chemical inertness—making them indispensable for applications that require reliability under extreme conditions.

Manufactured using cutting-edge diamond-tool CNC machining and atomic-layer polishing techniques, these windows can be produced in custom shapes, including ultra-thin disks, hexagons, D-shapes, and complex free-form geometries. We offer dimensional tolerances down to ±0.001mm, with surface roughness of less than 5 Å. These windows deliver exceptional performance across a broad electromagnetic spectrum, from ultraviolet (UV) to mid-infrared (IR) wavelengths.
