While pulsar wind nebulae (PWNe) and their associated isolated pulsars arecommonly detected at X-ray energies, they are much rarer at near infrared (nIR)and optical wavelengths. Here we examine three PWN systems in the Galacticplane - IGR J14003-6326, HESS J1632-478 and IGR J18490-0000 - in a bid toidentify optical/nIR emission associated with either the extended PWNe or theirpreviously detected X-ray point sources. We obtain optical/nIR images of thethree fields with the ESO - New Technology Telescope and apply standardphotometric and astrometric calibrations. We find no evidence of any extendedemission associated with the PWNe in any of the fields; neither do we find anynew counterparts to the X-ray point sources, except to confirm the magnitude ofthe previously identified counterpart candidate of IGR J18490-0000. Furtherobservations are required to confirm the association of the nIR source to IGRJ18490-0000 and to detect counterparts to IGR J14003-6326 and HESS J1632-478,while a more accurate X-ray position is required to reduce the probability of achance superposition in the field of the latter.
