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

12 Aug 2020

Knight Optical can offer Z-Cut Quartz Windows for use within the security industry.

We supply a range of Z-Cut Quartz windows for a range of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’s more, our Z-Cut Quartz Windows are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications.

Knight Optical supply precision optical components to customers within the security industry. Z-Cut Quartz windows can be used in the terahertz region for non-invasive scanning of individuals. These types of scans can detect objects such as weapons and are used in airports and other high-security locations.

Quartz is a birefringent material, which affects the polarisation of light passing through it, and is cut specifically along the Z-axis to maintain polarisation. Z-Cut Quartz is used in applications where quartz is an ideal material; yet changes to polarisation are required.

Typical specs:

Material:                                             Z-Cut Quartz (SiO2)

Shape:                                                  Circular windows, square windows

Dimensional Tolerances:              +/- 0.1mm

Parallelism:                                        < 3 arcminutes

Surface Quality:                                                               < 0.5 λ PV@ 633nm

Coating:                                               Anti-Reflective (AR) coatings for application bandwidth (if required)

All our Z-Cut Quartz Windows are fully inspected on their quality in our ISO 9001-certified, state-of-the-art Metrology laboratory, using our Zygo Verifire Interferometer and Trioptics PrismMaster. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
