Abstract

After several changes over the past two years, mid-Infra Red (IR) spectral band 3-4µm has been decided to use for LAPAN's IR camera module. Moreover, the IR camera only will equip with one microbolometer as the detector. The peat fire and Indonesia's volcano activities are two major missions of this experimental IR camera. Applying the generally used design process including the trade-off, the LAPAN's IR camera module has been made. Optical analysis as the initial step has been laid a solid foundation for subsequent process. A commercial process, in this cases Zemax, plays an important role during this design process. Meanwhile, mechanical design, the second step of designing, includes the structure / thermal analysis as well. Structure/Thermal analysis basically is to ascertain whether the LAPAN's IR camera module meets all the performance or not when operating in harsh condition. Once again, the commercial software, Thermal Desktop/Sinda Fluint, and Solidworks have been utilized for the analysis and design process. Electrical design as the last procedure is the least process done due to limited time. The spot diagram, encircled energy, and MTF graph shows that design of our refractive lens including the selected material meet the performance requirement. The natural frequencies as the mechanical analysis result indicate that our mechanical design is on the track. Meanwhile, for structure/thermal problem, the analysis tells the LAPAN's IR camera module will work well in space environment as well. Furthermore, the electrical design provides a good enough interface between the FPA detector and the electronics
