Concentrated photovoltaics is an app which generates electricity from sunlight - Knight Optical can offer you Stock and Custom Fresnel Lenses, for concentrated photovoltaic applications in a range of materials such as PMMA Acrylic and Borosilicate. CPV is an application which generates electricity from sunlight. The key difference between this technology and conventional photovoltaics (solar panels) is the inclusion of optical components. Utilising optical components which focuses the sunlight onto solar cells increases the efficiency of the electricity generation. Knight Optical provides fresnel lenses which 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 for CPV systems as it is very lightweight when used in a large size. Specialist grades of PMMA are also utilised which absorb the UV light and thus reduces the effects of solarisation i.e. the yellowing of the optical material due to exposure to UV.

Knight Optical has successfully launched a range of Stock Optical Domes for use in Pyronometers. Pyranometer/pyrgeometer are used for measuring solar irradiance. Typical applications being to understand where insulation needs to be within a building, climate studies and solar monitoring systems. A dome is essentially a window that has two parallel curves faces. Domes are used to shield the thermopile/ sensor used for making the measurements within a Pyranometer. Our domes are polished to high standards having good form error and high clarity with excellent transmission in the UV, NIR and FarIR spectrums allowing for accurate measurement. Capabilities: Domes are readily mountable, optically clear and manufactured to a high standard. Available from 5mm to 200mm in diameter and 0.25 to 10mm in thickness offering high transmission and extreme toughness for harsh environments. For more information read PDF

Germanium wafers are a semiconductor material & are for microelectronics - Germanium wafers are a semiconductor material & therefore are a smart choice for microelectronics. Due to its unique electric properties, it is widely used for sensors, solar cells and infrared optical applications. The wafers are also great for microelectronics as the space is limited and being available in 500μm or less it makes it perfect to achieve the high quality results required. It’s thermal conductivity makes it a good alternative to silicon. Our stock wafers are produced as thin as 500μm and provide exceptional surface quality. However, we can manufacture to a fully customised specification with a wafer thickness as little as 10 μm. Typical specifications of our germanium wafers are: 10mm – 150mm in diameter <500μm in thickness Doped and undoped Germanium
