Fused Silica Laser Protective Window
Fused Silica protective windows are specially designed optics made of Fused Silica optical glass, offering excellent transmission properties in the visible and near-infrared wavelength ranges. Highly resistant to thermal shock and capable of withstanding high laser power densities, these windows provide critical protection for laser systems. Their rugged design ensures they can withstand intense thermal and mechanical stresses without compromising the integrity of the components they protect.
