We present quasi-simultaneous multi-colour optical/near-IR photometry for 157 radio selected quasars, forming an unbiassed sub-sample of the Parkes Flat-Spectrum Sample. ... The spectral energy distributions of the radio- and optically-selected sources are quite different. ... We show that the colours of our red quasars lie close to the stellar locus in the optical: they will be hard to identify in surveys such as the Sloan Digital Sky Survey. ...

The optical scheme of the instrument is sketched in Figure 1 , it is designed to match the F/20 focal ratio of the TIRGO telescope. We have, following the optical path, the window of the dewar, the order sorting filter (not in figure), a field lens, in Calcium Floride, and the slit, in the focal plane of the telescope. ... The resolving power is (for first order of grating) of about 600 in the center of J band and 950 in the center of the K band, using a slit of two pixel (3.46 arcsec). ...
