Abstract

The Gemini Infrared Multi-Object Spectrograph (GIRMOS) will bring high-resolution integral-field spectroscopic and imaging capability to the Gemini North observatory. Designed to work with the Gemini North Adaptive Optics system, it has a multi-object adaptive optics capability that will provide increased resolution and sensitivity for the selected targets. The GIRMOS Calibration System (CAL) is an integral part of the GIRMOS instrument, providing photometric, spectroscopic and metrology calibration. A recent addition to GIRMOS is a field lens assembly (FLA), mechanically integrated with CAL, that provides a telecentric beam and optical shutter. This paper summarizes the final design, mechanical analysis, and optical tolerance analysis of the CAL/FLA subsystem.
