Paper Abstract

Spectroscopy is an essential tool in the astronomer's kit, probing the microscopic physics of astronomical objects. The Long-Wavelength Spectrometer (LWS) is one of two complementary spectrometers in the European Space Agency's Infrared Space Observatory (ISO). I discuss briefly the scientific considerations that drove the design of the LWS and describe the instrument itself. I then discuss how the instrument works and outline its photometric performance.
