WebThe spectrum of the combined beam is measured with an optical spectrum analyzer. The spectral interval uniformly distributes with 0.6 nm. In this work, only 32 wavelengths are acquired, and the numerical range of the combined wavelength is 18 nm, which changes from 1054.8 nm to 1072.8 nm. This result is obtained because we have used 32 channels ... An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building. Optical beam smoke detectors are often installed in warehouses as a cost-effective m… geotrax instructions
