If you can find a laser pointer with optics that can be dismantled
(usually older types), you may be able to transplant an IR laser diode
into it. Note however that the IR diode may well not work with the laser
pointer's power supply - the polarities of the laser and photodiode
are often different.

Monochrome cameras work best. Colour ones have IR cut filters which
greatly attenuate IR, although you will probably still get enough
through to see it. Most colour cameras (often easier to find than mono) can be converted
for IR use -  you can often  dismantle the lens assembly and remove
the IR filter, which will be a light blue-green tinted.
