Precision Optics & Optical Components for UAVs, ROVs & Robotics

Knight Optical is a leading global supplier of metrology-tested, ultra-high-precision optical components for high-spec UAVs (unmanned aerial systems), USVs (unmanned surface vessels) and UUVs (unmanned underwater vehicles). With over 30 years in the industry, we have worked with world-leading businesses on pioneering applications that have revolutionised the world of unmanned technologies.

Known for their ultra-high performance and dependability, our precision optical components are used globally within unmanned systems in military and defence industries, for survey and mapping purposes, for devices used by emergency services and across many more subsectors.

Our catalogue ranges from UV and visible optics through to infrared (IR) components. These include: lenses, windows and domes, beamsplitters, filters, mirrors, prisms, graticules, optomechanics, and much more.

Premium-Quality Custom and COTS Optical Components

Whether you need on-spec optical components for underwater, air or surface unmanned systems, our diverse, comprehensive catalogue meets a variety of needs.

For critical projects with quick lead times, our stock range of over 3000 optics (some of which can be edged down to meet dimensional requests) can be dispatched the very next day. Alternatively, if you need something with more of a bespoke approach, our custom-made options enable you to pick the size, substrate, thickness, and, if required, optical coating for a seamless, first-time fit in your end application.

To reinforce our quality-first ethos, all optical components are tested in our fully equipped, state-of-the-art Metrology Laboratory by a group of qualified technicians. The team uses our leading-edge spectrophotometers, interferometers, video imaging systems and other front-line devices to measure everything from surface flatness and wavefront quality to angular measurements and focal lengths. Finally, your components are sent to our discerning QA department for visual inspection before dispatch.

Precision Optics for Unmanned & Autonomous Vehicle Applications

Precision Optical Domes for ROVs

COTS and Custom Optical Domes and Windows for ROV/AUVs

We are a supplier of high-quality optical domes and pressure windows for submersible ROVs and AUVs undertaking a wide range of missions from shallow-water inspections to deep-sea exploration. The hemispherical construction of our dome windows makes the two optical surfaces an equal thickness apart, resulting in a naturally strong shape that gets tougher under pressure and is ideal for underwater applications such as ROV camera dome ports and submersible windows.

A variety of materials are available for different application requirements, including UV-grade fused silica, quartz and sapphire for harsh environments and infrared applications, and PMMA acrylic for lightweight and low-cost bulk manufacturing.
