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

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

Trotec presents T260 Infrared-Thermohygrometer. It has been designed and made as per the highest German quality standards. It has a high readability display. The DP mode provides simultaneous display of the dew point and surface temperature. Once the wall temperature is approaching or is lower than the dew point temperature, the user is warned by the T260 through an alarm tone and an optical laser signal. This alert function facilitates quick investigation of surface and detection of weak spots. The user can individually configure these alert states. Using a USB cable, T260 thermohygrometer can be connected to a PC. It provides MultiMeasure Studio Software, which is freely available in the downloads segment of uk.trotec.com. The software enables real-time transfer of T260's measured values both online and to the PC. Thus the values can be stored for analysis or reporting at a later stage. It has a continuous glass surface, which can be cleaned with ease.

Addressable heat detector with built-in short circuit isolatorDETECTO HT110 is an addressable heat detector designed to work as part of the Tiras PRIME A system. It can be configurated for "Fixed temperature" (A2 or B Classes) or "rate-of-rise" operation mode (A2R Class).
