... Near Infrared Camera and Multi-Object Spectrometer Instrument Handbook for Cycle 17 > Chapter 4: Imaging > 4.3 Focus History . ... The Pupil Alignment Mechanism (PAM) consists of an adjustable mirror in the NICMOS optical train that can be moved to make small corrections to the NICMOS focus and serves to properly position the pupil image of the telescope primary mirror onto the corrective optic. ... The NICMOS cameras were designed to share a common focus with the PAM close to its zero position. ...
