Instruments and Projects
iLocater
A diffraction-limited high-resolution NIR spectrograph under development for the Large Binocular Telescope.
SDSS Robotic Focal Plane Systems (FPS)
The Focal Plane System (FPS) units for SDSS-V replace the traditional Sloan Survey hand-plugged fiber plates with 500 robotic fiber positioners.
Multi-Object Double Spectrographs (MODS)
The Multi-Object Double Spectrographs (or MODS) are two facility UV-to-Near IR spectrographs for the Large Binocular Telescope.
GSpec
GSpec is a technology demonstration of the dual-aperture fiber nuller.
DESI Sky Continuum Montitor
The DESI Sky Continuum Monitor System tracks the night sky brightness to dynamically adjust exposure times to maximize DESI observing efficiency.
DESI Commissioning Instrument
The DESI Commissioning Instrument jump-started commissioning of DESI by completing many critical on telescope tests before DESI was installed in 2019.
DEdicated MONitor of EXoplanets and Transients (DEMONEXT)
DEMONEXT is a 20-inch (0.5-m) robotic telescope for photometric monitoring of transiting exoplanets and transient sources.
Korean Microlensing Telescope Network Cameras (KMTCam)
The three KMTNet prime focus CCD cameras are dedicated to gravitational microlensing searches for exoplanets on custom-designed 1.6m telescopes.
KPNO/CTIO Ohio State Multi-Object Spectrographs (K/COSMOS)
The Kitt Peak/CTIO Ohio State Multi-Object Spectrographs (K/COSMOS) are modified versions of the OSMOS spectrograph for the 4-m Mayall and Blanco telescopes.
Ohio State Multi-Object Spectrograph (OSMOS)
The Ohio State Multi-Object Spectrograph (OSMOS) is the workhorse facility optical spectrograph at MDM.
LBT f/15 Rigid Secondary Mirror
The LBT f/15 Rigid Secondary Mirror enabled the LBT's MODS and LUCI facility instruments to get on sky before the adaptive secondary mirrors arrived.
The DEdicated MONitor of EXotransits (DEMONEX)
DEMONEX was a 20-inch robotic telescope for dedicated exoplanet transit monitoring.
Kilodegree Extremely Little Telescope (KELT)
KELT, OSU's first fully-robotic telescope, eventually discovered 26 transiting exoplanets around bright stars.
LBT Primary Mirror Aluminization System
The LBT Primary Mirror Aluminization system is used to put a fresh aluminum coating on the LBT's 8.4-meter diameter primary mirrors.
Buckeye 12-position Filter Wheels
The ISL built three copies of our 12-position "Buckeye" automated filter wheel for use at CTIO and MDM between 2003 and 2008.
Yale 1m 4K CCD Camera (Y4KCam)
Y4KCam was a wide-field CCD imager and filter wheel system deployed on the CTIO Yale 1-m telescope for the SMARTS project.
RETROCAM
RETROCAM was an auxiliary CCD camera that could be rapidly inserted into the optical beam of the MDM 2.4 m telescope to enable concurrent synoptic observing.
CCD Camera Systems
OSU built a number of custom and commercial CCD camera systems for observatories on four continents.
