Instruments
This page shows Gemini's current, retired and future instrument complement. The expected instrument availability for the coming semester is given in the current Call for Proposals; information for the current and previous semesters (and the next semester when finalised) can be found in the schedules section.

Instruments that are in the process of being built, tested, and commissioned are listed in the tables above. Information about Gemini's instrument development program, including plans for the future "Aspen" instruments, may be found on the Future Instrumentation Plans page. A summary of Gemini's ongoing adaptive optics program is also available.
The following instruments are no longer available for science use. Their web pages will be available indefinitely, to support data processing and analysis of distributed and archived data, but may not be updated.
- The Acquisition Cameras are no longer offered for science use.
- bHROS, a high-resolution optical spectrograph, has been retired.
- NIRSPEC (near-IR spectrograph on Keck) was offered to the Gemini community for limited use during 2000-2001.
- OSCIR (mid-IR imager/spectrometer) was offered as a visiting instrument, loaned by the University of Florida for early science on Gemini North and, more recently, on Gemini South. It was replaced by the facility mid-IR instruments Michelle and T-ReCS.
- Hokupa'a-36 / QUIRC (natural guide star adaptive optics system and its near-IR camera) was offered as a visiting instrument, loaned by the University of Hawaii for early science on Gemini North. It is has since been replaced by the facility AO system Altair.
- Flamingos-I (near-IR imager and multi-object spectrometer) was offered as a visiting instrument, loaned by the University of Florida, on Gemini South.
- CIRPASS (near-IR Integral Field Unit spectrograph) was offered as a visiting instrument, loaned by the University of Cambridge, during 2002-2003.
