As new player in Infra Red (IR) sector, uncooled, small, and lightweight IR Micro Bolometer has been chosen as one of
payloads for LAPAN’s next micro satellite project. Driven the desire to create our own IR Micro Bolometer, mission
analysis design procedure has been applied. After tracing all possible missions, the Planck’s and Wien’s Law for black
body, Temperature Responsivity (TR), and sub-pixel response had been utilized in order to determine the appropriate
spectral radiance. The 3.8 – 4 μm wavelength were available to detect wild fire (forest fire) and active volcanoes, two
major problems faced by Indonesia. In order to strengthen and broaden the result, iteration process had been used
throughout the process. The analysis, then, were continued by calculating Ground pixel size, IFOV pixel, swath width,
and focus length. Meanwhile, regarding of resolution, at least it is 400 m.
The further procedure covered the integrated of optical design, wherein we combined among optical design software,
Zemax, with mechanical analysis software (structure and thermal analysis), such as Nastran and Thermal Desktop /
Sinda Fluint. The integration process was intended to produce high performance optical system of our IR Micro
Bolometer that can be used under extreme environment. The results of all those analysis, either in graphs or in
measurement, show that the initial design of LAPAN’S IR Micro Bolometer meets the determined requirement.
However, it needs the further evaluation (iteration). This paper describes the initial design of LAPAN’s IR Micro
Bolometer using mission analysis process
