What is optical window?

Optical Windows are flat, plane-parallel, transparent optical surfaces designed to protect sensors and other electronic instruments from environment conditions.

Optical Window selection considerations include material transmission properties as well as scattering, strength and resistance to certain environments. Their use should not impact on magnification of a system. Optical Windows can be optically polished and incorporate an element for diffusing light source to control illumination.

AR coatings can be applied to ensure maximum transmission performance for a particular wavelength. The windows are made in a range of materials including UV Fused Silica, Quartz, IR Crystals and optical glasses. Our optical window properties include x-ray protection, non-browning to UV light and light transmission from deep ultra violet to far-infrared.

Optical window can be a protection of original when it's in two physical environments. And there is almost no effect on visible light,to coating on the surface of windows could increase the transmittance,the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS).Optical glass flat with coating can enhance the light penetration strength,and own function of waterproof ,dustproof,and scratch-proof.

Types of Optical Windows

  • Ultraviolet Windows

Ultraviolet windows are often used with laser instruments or other applications in medical, industrial and defense areas. Sydor Optics can help determine the best substrates, UV coatings, and other optical properties and custom manufacture UV windows to best meet your specific requirements and applications. Anti-Reflective (AR) coating is available for one or both surfaces.

  • Visible Windows

Visible windows are designed for use in the visible spectrum: the type of light visible to the human eye. Visible windows are ideal for protecting optical systems and other optical components, imaging or display systems, or other applications. Sydor Optics can custom manufacture visible windows in a variety of shapes, sizes, and substrates for various optics applications, including those with extreme temperatures or other challenging conditions. AR coating is available for one or both surfaces.

  • Infrared (IR) Windows

Infrared windows are often used in FLIR, FTIR spectroscopy, medical systems, thermal imaging, or other optics applications within the infrared light spectrum. IR windows can help protect your employees and equipment. Sydor Optics can custom manufacture IR windows in a variety of shapes, sizes, substrates, and coatings for various infrared applications. AR coating is available for one or both surfaces.
