Knight Optical’s Z-Cut Quartz Windows for the Security Industry

13 Feb 2020

Due to its ability to transmit above 50µm, Quartz is often the substrate of choice for security systems that operate in the terahertz region. As such, our Z-Cut Quartz Windows are commonly specified for integration with devices such as industry-leading full-body scanners found at airports. For such a discerning operation, the components specified within this potentially life-saving and disaster-prevention technology must be of the utmost standards. Thanks to our knowledge of optical components and quality first ethos, our optics are trusted within commercial security industries across the world and have been an industry favourite for 28 years. 

Our leading status for optical components, such as Z-Cut Quartz Windows, does not only stem from our widespread application knowledge; it also derives from our wide range of readily available stock and in-house customised capabilities. For our Z-Cut Quartz Window range, we stock a variety of diameters and thicknesses – as well as right-hand and left-hand options – ready for next-day dispatch. Furthermore, for projects requiring prompt solutions and specific sizes, components within our comprehensive stock range can be edged to smaller diameters and Anti-Reflective (AR) coatings can also be applied. What’s more, if required, Knight Optical also provides Z-Cut Quartz Windows as mounted optics. 

 Alongside a broad range of online stock, we also supply custom-made Z-Cut Quartz Windows, tailored to individual applications' precise requirements. From concept to completion, our team of Technical Sales Advisers work with you to fabricate the optics ideally suited to your device. This tailored service allows you to specify the dimensions, thicknesses, tolerances and optical coatings to enable optimum operation of your device. To find out more about our customised optical components, get in touch with a member of the team today.
