Aspects of Design and Development of a Near Infrared Photometer for Low Altitude Astronomical Sites

Abstract

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.
