Protective Windows

  • Introduction

Protective Window


Protective Window is applied to isolate different physical environments while allowing light to pass through. When selecting windows, please consider the material, transmission, scattering, wave front distortion, parallelism and resistance to certain environment. We offer all kinds of windows, which are made from different materials.

Single layer, multiplayer anti-reflecting coatings on optical windows are also available upon request.
