In order to fill the void of observation of bright near infrared astronomical
sources, we propose a Near Infrared photometer operating from a low latitude
astronomical site. As part of this thesis work, design decisions defining the
specifications of such a photometer is presented. InGaAs single pixel detectors and IRWG (Infrared Working Group) recommended filters are identified
to be capable of achieving high signal to ratio while observing bright sources
with short integration duration. Design, development and tests of various
components of this photometer are discussed.
