1. Introduction on Optical Calibration Laboratory
Optical Calibration Laboratory building was completely built in 10 March 2006. It was the pioneer lab in Malaysia that has capability to calibrate optical system of a satellite. This lab was fully operational in 6 April 2006 after the cleanroom located inside is commissioned. It is a double storey building with control room for the clean room, dust control area, loading area in ground floor while the first floor is research office.
2. Optical Calibration Laboratory Main Function
The main purpose for this facility is dedicated to the characterization and calibration of electro-optical system. The clean room was designed to meet Class 10,000 of Federal Standard 209B or equivalent to class 7 in ISO classification to regulate the environment for calibration activities involving satellite that requires a controlled environment in terms of temperature, humidity and particle. Besides, the flooring is finished with epoxy layer on top as a control for electrostatic discharge (ESD) and there is grounding connection at each corner of the clean room. The Clean room is operating with environmental condition temperature 18 ± 2 °C, humidity 50 ± 5%, dust particles smaller than or same size as 0.5μm is less than 10 000 units/ft3, grounding connection resistance less than 10 Ω, lighting condition 500 Lux, and safety control with CCTV and restricted access pass.
