MOSFIRE is a Multi-Object Spectrometer for the Near Infra-Red

(wavelengths ~0.975-2.40 μm)

• We are deep in the component fabrication and procurement phase.

• Optics: Good progress at COSI, UCO, and other suppliers

• Mechanical & Facilities: – Lots of fabrication complete and in-process at

Caltech/UCLA shops as well as outside shops for larger components such as dewar, structure.

– Clean room installed in Synchrotron high bay– Test & Build Stand fabrication complete

• Software: good progress; waiting for hardware

• Electronics: ramping up, EE hired @ UCLA1st Cold Test in planned for May 5, 2008
