MOSFIRE Multi-Object Spectrometer For InfraRed Exploration

• On Keck I, MOSFIREprovides:– 46 slits over 6.1' x 3' field

using configurable slit mask unit

• Unique capabilityworldwide

• First light: April 4, 2012• Funding: NSF TSIP and

Gordon and Betty Moore• Has become most

popular instrument on Keck I

January 22, 2014
