Optical Gas Detection Open Path (line-of –sight) Gas Detection employing electro-optical "spectral finger-print" analysis of the atmosphere uses the Differential Optical Absorption Spectroscopy (DOAS) technique in a unique (patented) method. The use of discriminative UV and IR narrow band filtered sensors enables the detection， identification and concentration determination of Flammable & Explosive gases migrating in the atmosphere， at concentrations well below their explosive levels. The specific systems developed for detection of flammable or toxic gases employ a flash or filament light source， which is in communication with a detector that responds to the attenuation in the light intensity caused by the presence of the gas. This line of Optical Gas Detection Systems known as SafEye has been successfully introduced into the High Risk/High Value markets. 2. Optical Flame Detection Flame Detection employing electro-optical analysis of the electromagnetic radiation emitted by flames in the Ultraviolet and Infrared spectral bands. The patented spectral analysis of the Flames radiation signals includes frequency and time domain analysis， cross correlations and ratios between the various sensor inputs. Unique background radiation analysis enhances the flame detection accuracy in a cluttered environment that contains various emitting sources like: direct solar radiation， heaters and burners， light projectors， high voltage sparks and welding radiation， extreme temperature conditions. This line of Optical Flame Detectors named SharpEye was developed and introduced into the safety and high risk/high value fire protection markets. The SharpEye series includes UV， UV/IR， Triple IR (IR3) and CCTV Optical Flame Detectors. 3. Explosion & Fire conditions Detection Explosion & Fire conditions can be detected very early by monitoring their environmental characteristics such as: changes in temperature and pressure caused by gaseous decomposition processes， radiation emitted during such processes， decomposition by-products that can be monitored at very low concentrations in air. Monitoring combustion products such as: CO2， CO， NOx， HC (unburned hydrocarbons)， etc.， at very low concentrations in air (at PPM levels) enables very early and reliable detection of these conditions. The SafEye line of Optical Gas Analysis Systems includes UV and IR specific models. 4. Military Explosion Detection and Suppression Systems SAFE line of military vehicle fire and explosion detection and suppression systems was developed by Spectrex Inc. in order to protect personnel from skin burns and pressure shock. The systems suppress gas or vapor explosions in less than 150 milliseconds， with a speed of response of less than 3 milliseconds. Suppression is activated in less than 5 milliseconds to discharge and disperse the agent， thus providing a uniform extinguishing concentration. The systems have been incorporated successfully in thousands of military vehicles worldwide
