This thesis presents work undertaken in the design, build, characterisation and first results of a new instrument for the optical characterisation of wide band gap materials by their luminescence. Optical spectroscopy is a promising method for investigating material properties due to its non-destructive nature and high sensitivity. The ability to relate to a material's optical properties to its structure and composition is highly desirable in Materials Physics applications. Spatial information is lost when measuring heterogeneous samples due to the convolution of spectral information from different regions within the sample. Though the combination of imaging and spectroscopy spatially resolved data can be a. In this work the spectro-radiometrically calibrated instrument HeLIOS (Hyperspectral Imaging for Optical Spectroscopy) is introduced. This instrument has allowed the collection of spatially resolved radiometrically calibrated photoluminescence investigations on a number of wide band gap materials.
