    LOTUS (LOw-cosT Ultraviolet Spectrograph) is a low resolution optical-near UV spectrograph. The design is very simple, with no moving parts. It provides wavelength coverage from 3200 to 6300 Angstroms at a dispersion of 4.7 Angstroms/pixel. The slit has "narrow" (2.5 arcsec x 95 arcsec) and "wide" (5 arcsec x 25 arcsec) regions to allow optimal spectral resolution or flux calibration.

    Range: 3200-6 300Å
    Spatial Pixel Scale: 0.6 arcsec/pixel
    Wide Slit: 5''x25''
    Narrow Slit: 2.5''x95''
