The light in the range from 0.75㎛ to 1000㎛ electromagnetic waves are categorize as infrared.The categorization of infrared ranges are NIR (below 1.4㎛, Near Infrared), SWIR (1.4~3㎛, Short-Wavelength Infrared), MWIR (3~5㎛, Mid-Wavelength Infrared), LWIR (8~14㎛, Long-Wavelength Infrared), and FIR (longer than 20㎛, Far Infrared).This categorization is based on atmospheric transmitting characteristics of infrared light, which is very useful for observation owing to its high transmittance. User can select the range among different infrared bands according to the purpose of their system.

Surveillance system and fire protection 1) Surveillance for intrusion and fire2) Saving a life in fire circ㎛stance3) Safety driving for automobile and train at night4) Surveillance for taking off and landing aircraft at night5) Surveillance for ecosystem and environment Driving assistance 1) Driving assistance for automobile, bus and truck at night Importance of Thermal Image [Commercial / Civilian]Variety of uses in field of earth exploration, disaster prevention and astronomical observation in commercial / civilian.[Earth exploration]Research the variation of the weather regarding the evaporation of water vapor and soil moisture by using calibration of infrared images from various wavelength bands of infrared.[Environment]Research the status of biological resources or mineral reserves, exploration, marine resources and ocean currents.[Disaster prevention]Thermal infrared images can find the origin of forest fires or volcanic eruptions. Research the oil spill detection and monitoring red tides if different of IR band information are collected.[Industry and daily life]Applicable to building maintenance and security systems[Military]There is very important to detect the thermal image of infrared wavelength band of in the field of the military. Once using the infrared image and visible light image, it can improve detecting performance and maximize reliability. In addition, the infrared observation is able to detect the heat of the target itself, the infrared imaging is possible for poor condition during the night and is effective for continuous monitoring all day and night Infrared(Cooled) Division MWIR MWIR LWIR Measure InSb T2SL T2SL Wavelength range MWIR 3~5㎛ MWIR 3~5㎛ LWIR 7.7~9.4㎛ Cooling Required 80K 130K 80K Array size 320×256, 15㎛320×256, 30㎛640×512, 15㎛1280×1024, 10㎛1280×1024, 15㎛ 640×512, 15㎛1280×1024, 10㎛ 640×512, 15㎛1280×1024, 10㎛ Operability > 99.5 % (Typ.>99/8%) > 99.5 % > 99.5 % Comment Very mature technology Useful in light-weight devices such as handheld thermal imaging, drone & UAV systems Infrared(Uncooled) Measure Bolometer InGaAs Wavelength range LWIR 8~14㎛ SWIR 0.9~1.7㎛ Vis-SWIR 0.X~1.7㎛ QE(Quantum Efficiency) – 85% @ 1.4㎛ Array size 384×288, 17㎛ 640×480, 17㎛ 384×288, 12㎛ 640×480,12㎛ 1024×768,12㎛ 640×480, 15㎛ Operability ≥99% > 99.5 % Max frame rate 60Hz 50Hz Cooling type TECless TEC Company Profile Overview CEO’s Message History Location Product Product lines Cooled Detector Uncooled Detector InGaAs(SWIR) X-ray R&D Infrared X-ray System Roadmap Public Relations i3system News Contact Headquarter : 69, Techno 5-ro, Yuseong-gu, Daejeon, Korea Jang-dong : 26-32 Gajeongbuk-ro, Yuseong-gu, Daejeon, Korea Munji-dong : 435, Expo-ro, Yuseong-gu, Daejeon, Korea Sales (Munji-dong) : 070-4944-7733 / 070-4944-7734 E-mail : marketing@i3system.com Investment Relations Tel : 070-7784-2506, FAX : 042-931-2555 Location
