Optical Window
Diamond offers the broadest transmission spectrum among current solids, with excellent transmission from 225nm UV to 25μm IR, excluding 1.8μm-2.5μm, and into microwaves. High hardness, thermal conductivity, chemical stability and low expansion make it ideal for modern infrared windows. We supply various sizes and vacuum-brazed flange windows, with customization available.
