The Spartan Infrared Camera
  • Built in MSUs astronomical instrumentation lab.
  • 40962 pixel detector array.
  • Highest possible angular resolution.
  • Wide field of view.

Why build a 4-meter diameter ground-based
telescope?

The Electromagnetic Spectrum and Absorption by
the Earths Atmosphere
Why build a 4-meter diameter ground-based
telescope?

The Electromagnetic Spectrum and Absorption by
the Earths Atmosphere
Why build a 4-meter diameter ground-based
telescope?
Light from outer space cannot penetrate below
this altitude.

  • Telescopes must be in space to observe at x-ray,
    ultra-violet, or far-infrared wavelengths
  • Chandra X-Ray satellite
  • Hubble Space Telescope
  • Spitzer Infrared satellite

Ground-based optical-IR telescopes complement
space observatories
Why build a 4-meter diameter ground-based
telescope?
We use ground-based telescopes at these
wavelengths.

Why build a 4-meter diameter ground-based
telescope?
We use ground-based telescopes at these
wavelengths.
  • SOARs infrared images as sharp as Hubbles!
