What Optical Components are Used for Automation? 

Our optics are specified for some of the world's most innovative automated applications. From the automobile sector to agricultural and industrial fields, there's an abundance of sub-divisions within the robotics and automation sector that rely on us for our premium-quality optical components. For example, our custom-made and stock Polarising Beamsplitters are regularly specified for machine vision systems within the food processing sector. And, our Optical Filters and Cover Windows are often selected for automated applications such as Light Detection & Ranging (LiDAR) amongst cars and agricultural vehicles such as tractors. 

Other examples of our work include the development of project-specific optics for sensors within Formula 1 vehicles and an optical assembly to make cancer screening more convenient and accessible.

In-House, State-Of-The-Art Metrology Laboratory 

Our Metrology Laboratory testing allows us to offer optical components of superlative quality. To guarantee customer satisfaction, our team of technicians assemble test data from each batch test and dispense this evidence with corresponding components. Our advanced metrology equipment plays a crucial role in enabling our technicians to accurately measure optical fundamentals — such as transmission, reflection, optical density, focal length and radius of curvature, to name but a few. 

Our devices include: 

• Varian Cary 5000 UV-VIS-NIR spectrophotometer with UMA attachments – learn more about our Cary 5000 here

• Agilent Cary 660 FTIR spectrophotometer

Qualit Assurance   

As a customer of Knight Optical, you will benefit from an exceptional commitment to quality in all respects. Your specifications are vitally important to us, which is precisely why pre-dispatch testing is rigorous to the highest degree. 

Our UKAS-accredited Quality Assurance (QA) department visually inspects every component before dispatch to assure conformance with our customers' surface quality specifications. Measured against a MIL-RF-13830- and MIL-M-13508-compliant scratch/dig master for definitive quality assurance, any component that is not fit for purpose or displays any defects is immediately rejected. Although these rejections never make it past the first stage of manufacture, our 99.9% pass rate indicates our high-level of sustainability and initial quality control.
