Ball Lenses are widely used for focusing & coupling light into & out of fibres. With the high refractive index of Sapphire (Al2O3) material, it yields a low spherical aberration that can be used in the range of UV from 200nm up to 5µm, and with it being one of the hardest materials they are resistant to damage. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Typically used in pairs, where one lens acts as collimator for the second to focus the light back into the coupled fibre. Ball Lenses are manufactured from a single substrate of glad and therefore, depending on the geometry of the input source, can focus or collimate light. Half Ball Lenses can also be used as an interchange with a full ball lens for more compact designs. Read the PDF for more information...

Knight Optical can offer Ground Glass Diffusers for use within Photography. We supply a range of Ground Glass Diffusers 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. Knight Optical supply precision optical components to customers within photography. Ground Glass Diffusers are used in to diffuse the flash from cameras to prevent photos with harsh light and hard shadows to soften and improve the appeal of the image. Diffusers are also used in lightning systems to prevent glare from computer screens, the manufacture of lightboxes for advertising, viewing x-rays, and other applications.

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.
