This paper presents the TNO share of the development of the HIFI Alignment Camera System (HACS), covering the opto-mechanical and thermal design. The HACS is an Optical Ground Support Equipment (OGSE) that is specifically developed to verify proper alignment of different modules of the HIFI instrument during on-ground thermal (vacuum) testing of the ESA Herschell spacecraft.
