We present the results of an infrared survey of QSO fields at z=0.95 , 0.995 and 1.5 .
Each z < 1 field was imaged to typical continuum limits of J=20.5 , K ^ { \prime } =19 ( 5 \sigma ) , and line fluxes of 1.3 \times 10 ^ { -16 } ergs/cm ^ { 2 } /s ( 1 \sigma ) in a 1 % interference filter .
16 fields were chosen with z \sim 0.95 targets , 14 with z \sim 0.995 and 6 with z \sim 1.5 .
A total area of 0.05 square degrees was surveyed , and two emission-line objects were found .
We present the infrared and optical photometry of these objects .
Optical spectroscopy has confirmed the redshift of one object ( at z=0.989 ) and is consistent with the other object having a similar redshift .
We discuss the density of such objects across a range of redshifts from this survey and others in the literature .
We also present number-magnitude counts for galaxies in the fields of radio quiet QSOs , supporting the interpretation that they exist in lower density environments than their radio loud counterparts .
The J-band number counts are among the first to be published in the J=16–20 range .
