24 Aug 2021

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: <40-20 Scratch/Dig
< 0.5 λ PV@ 633nm
