Abstract

The spectrophotometer presented here combines the advantage of aperture photometry with spectrophotometry to obtain colours of extended objects over the range of 3500–6000 Å. The spectrophotometric resolution matches the resolution of intermediate-band interference filters of about 140 Å FWHM.
