Knight Optical offers a range of precision optical components for use in IPL (Intense Pulsed Light) applications. The most common usage of IPL systems are typically used as photo epilators.Custom Ceramic Reflectors are a key component for this application. The xenon flash lamp which are typically used emit light in 360 degrees. However utilising ceramic reflectors which are light reflectors with a U channel means that light which would normally be wasted i.e. shining backwards is now refocused down into the filters and light guides. Knight Optical provides ceramic reflectors which are typically moulded from alumina. This choice of material is down to its ability to withstand thermal stresses and high reflectivity values.

Knight Optical can offer you Stock and Custom Fresnel Lenses, for use within Magnification Displays in a range of materials such as PMMA Acrylic and Borosilicate. We supply a range of Fresnel Lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Our Fresnel Lenses consist of a flat surface with interspace concentric steps whereby each step corresponds to the surface of a conventional lenses. PMMA Acrylic is a preferred material type of the Magnification Displays as it is very lightweight when used in a large size. Fresnel lenses is a common focal length equivalent to a traditional lens, but with a fraction of the thickness. Additionally, because the lens is so thin little light is lost by absorption.
