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.

Knight Optical can offer Custom Homogenizing Rods for use within Fluorescence Imaging. Knight Optical supply precision optical components to customers in the medical industry for applications such as fluorescence illumination, microscopy and imaging. Homogenizing Rods are used within the application of surgical procedures; within systems designed to help identify which tissues have been exposed to the fluorescent indicator. The Light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to channel the light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipes critical angle; this defines the angle of acceptance which the total internal reflection will occur at. With this it helps to control the light source being used in medical systems.

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...

Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Sapphire is birefringent and if its use is for critical optical application then the crystal might have to be cut along the zero degree plane, or C-Cut. Random cut is usually cut along a plane that is 60° off-axis as the growth in this direction is the easiest to grow. Random cut is anything that is not the C-Cut angle. Sapphire can fluoresce depending upon the concentration of other minerals within the lattice, for example Iron (Fe) or Chromium (Cr). Clear Sapphire might fluoresce orange when illuminated by UV light if impurities are in the crystal. Fluorescent free Sapphire has to be grown from 'pure' feedstock and seed and in an environment that cannot place impurities into the lattice. Click PDF link to read more …...
