Frequently Asked Questions (FAQs)
What do Optical windows consist of and what materials are optical windows made from?
Optical windows are flat components that, being optically transparent, permit the passage of light with no significant distortion and protect the components from such light. They are found in laser applications, projection systems, metrology, microscopy, and any photonics. Such materials are represented by, but not limited to – crown glass, flint glass, fused quartz and, high purity quartz selected either for transmission in the ultraviolet, visible or infrared (IR) spectrum, abbe number or chromatic dispersion. The optical windows are customized to various sizes and thicknesses to meet the focal length and mounting requirements and are often given finishing such as anti-reflection coatings for better throughput and low reflection.
How can a custom made optical window be distinguished from an off-the-shelf window?
The replacement of standard windows with custom optical glass allows optical engineers to impose specifications for thickness, quality, and finish that can take into consideration the performance that the mounting materials are to provide. In most cases, stringent adherence to the surface and transmitted wavefronts, as well as thickness, is achieved only under particular regimes of custom optics that mitigate any distortions of measuring instruments as used in imaging systems. These practices can be provided in both massive quantity production and larger sizes suitable for the equipment within which the components are to be integrated. This allows a selection of more cost-efficient materials such as fused quartz, or particular light glasses for deep ultraviolet or infrared region of the spectrum. Custom Coatings or Edge Treatments are various polish techniques that allow for such sheer glass to be embedded in its construction.
What is the reason why quartz and fused quartz have become so popular for optical windows?
It’s demonstrably true that Optical transmission through quartz or fused quartz extends from dense ultraviolet radiation, through visible light and into some parts of infrared. This low absorption refractive material is compatible with quiet a few applications such as UV sensitive microscopy, lasers among others. Quartz and fused quartz offer excellent transmission because of their nature which is free of color and they absorb light very little. Also thermal conductivity and extremely low coefficient of thermal expansion are advantageous to the use of these materials in high temperatures lasers and metrology in general. Often in comparison with denser silicate glass optics, quartz optics offers advantages for infrared and ultraviolet lasers because such materials do not suffer from aberration and thermal expansion as much.
How do I go about choosing reflective elements and their coatings suitable for use in my optical set-up?
When choosing surfaces for mirrors, substrates (glass materials, such as silica or metallic elements) should be considered, as well as their parameters – surface geometry (flat, curved inwards or outwards) and suitable coatings. There are different types of coatings, for instance, metallic which provides broad-band reflection, dielectric which is optimal for a definite wavelength such as infrared or ultraviolet. Types of special windows and lenses vary. And in order to improve this situation Anti-reflective layers are applied. If you’re developing an OEM or short run system consider using robust coatings that comply with ITAR requirements if necessary. It is also advisable to carry out optical simulations for the elements to be designed in terms of reflectance and phase response in order to avoid deformations and achieve high optical quality.
What implications do the infrared and ultraviolet concerns have on the selection and manufacturing of the custom optical glass?
Material and coatings selections are led by considerations about the IR and UV transmissions: fused silica and selected optical crystal materials are ultraviolet transparent, while special glasses or optically transparent materials are used in the infrared region. The additives in the custom optical glass, the density of its composition and other factors are all needed to adjust light transmission and the abba number, which in turn change the chromatic dispersion of the systems, together with their focal length. For IR laser systems, it is important to use materials that will not thermally distort after being exposed to the laser input. Anti-reflective coating and modeling techniques are also used to improve the efficiency of the optical system by decreasing the reflectance in the specified frequency band.
