Introduction

MIRSI is a 2-20 micron camera and grism spectrograph built by Boston University. MIRSI was recently upgraded by IR Labs with a closed-cycle cooler to replace its liquid nitrogen and liquid helium cryostat, allowing MIRSI to be used interchangeably with any other IRTF instrument. It is currently being further refurbished by IRTF with a new array controller and an optical channel called MOC (similar to MORIS on SpeX). MOC will allow simultaneous visible light imaging with MIRSI and serve as a visible light guider for MIRSI.
