  Submillimetre and millimetre-wave surveys with Herschel and the South Pole
Telescope have revolutionised the discovery of strong gravitational lenses.
Their follow-ups have been greatly facilitated by the multi-wavelength
supplementary data in the survey fields. The forthcoming Euclid
optical/near-infrared space telescope will also detect strong gravitational
lenses in large numbers, and orbital constraints are likely to require placing
its deep survey at the North Ecliptic Pole (the natural deep field for a wide
class of ground-based and space-based observatories including AKARI, JWST and
SPICA). In this paper I review the current status of the multi-wavelength
survey coverage in the NEP, and discuss the prospects for the detection of
strong gravitational lenses in forthcoming or proposed facilities such as
Euclid, FIRSPEX and SPICA.
