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

Knight Optical can offer UV Fused Silica Lenses for Flame Detection Applications. UV Fused Silica can be used in Flame Detection Applications, due to its high transmission into the NIR range (approximately <92% avg 400-2000nm) meaning that a clear distinction can be made between different wavelengths of light. UV FS also has a very low coefficient of thermal expansion 0.55x10-6K-1 at 300K) compared to N-BK7 (7.1x10-6K-1), meaning that it can still provide optical performance under high temperature. UV FS also has a high melting point compared to N-BK7, providing further protection for your application in high temperature environments. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for more info

The Patol Linear Heat Detection Cable (LHDC) is designed to provide early detection of fire and overheating in circumstances where other forms of detection would not be viable, either due to inability to sustain the environment requirements or through prohibitive costs. Patol also offers a Line Type Heat Detector system.

The Patol Infra-Red Heat Detectors are designed to provide an early warning of fire or overheat conditions of material being transported on conveyor systems. The unique principle of operation will detect black body infra-red emissions at low thermal energy levels.
