MIKE Specs

Telescope:

• Focal ratio: f/11

Scale:

• Effective focal ratio:
  • Blue Camera - f/3.9
  • Red Camera - f/3.6

• At Detector:

• Blue Camera - 8.2 pixels/arcsec (0.12 arcsec/pixel)
• Red Camera - 7.5 pixels/arcsec (0.13 arcsec/pixel)

Slit Lengths:

• 5 arcsec for complete wavelength coverage (all echelle orders)
• Note that the instrument is fixed on the Nasmyth platform and therefore the slit remains at a fixed angle of 30 degrees.

Detectors:

• Blue Camera - Lincoln Labs CCD: 2048x4096 (15 µm pixels)
• Red Camera - SITe ST-002A CCD: 2048x4096 (15 µm pixels); Q.E. 

Readout Noise:

• Blue Camera - ~2 electrons/pixel
• Red Camera - ~3.5 electrons/pixel

Wavelength Range:

• Blue Camera: 3200-5000 Å
• Red Camera: 4900-10000 Å

Resolving Power:

• 0.35 arcsec slit: 83,000 (blue), 65,000 (red)
• 1.0 arcsec slit: 28,000 (blue), 22,000 (red)

Å/Pixel:

• Blue camera: ~0.02
• Red camera: ~0.05
