Protective window

Optical protective windows are designed to shield sensitive lenses, sensors and optical systems from dust, moisture, debris, mechanical impact and chemical corrosion.

Common applications cover laser equipment, infrared thermal imaging, machine vision, industrial inspection, medical instruments, aerospace and surveillance cameras. They also serve as viewports for high-temperature, vacuum and harsh industrial environments.

Available in diverse materials including sapphire, CaF₂, BaF₂, fused silica and optical glass, with customized size, polishing and anti-reflection coatings to meet different spectral and environmental requirements.
