    Visible Windows

    Visible Windows are Optical Windows designed for use in the visible spectrum. Visible Optical Windows are designed to prevent electronic sensors, detectors, other sensitive optical components from being saturated or damaged by light. Visible Windows are ideal for use in imaging applications or as protective displays for industrial or environmental applications. Visible Optical Windows do not introduce magnification power into a system. Visible Windows should be selected based on material transmission or mechanical properties.

    Edmund Optics offers a wide range of Optical Windows, including a variety of Visible Windows. Edmund Optics’ Visible Windows are available in a variety of glass or plastic substrates. Edmund Optics’ Visible Windows are designed for a wide range of applications, including those requiring high durability or operating temperature ranges. Plastic Visible Windows are light weight, cost effective solutions for applications requiring strong mechanical properties. Glass Visible Windows are ideal for applications requiring superior optical properties or operating temperature ranges.
