This is called "Different Wavelengths" and expresses a diagonally suspended series of shards of mirrors and filters, held together by a clear sheet, interrupted with dark bars like a barcode. "Infra"-red light enters and is reflected by the top part, whilst the bottom is illuminated by ultraviolet. The "barcode" is also intended to be read as spectral lines (used when deducing the composition of objects using chromatography), as well as a pun on the word "bar". Also with the alternating gauze and mirrors alluding to filtration and separation. The "red light" also alluded to the context of the project, London's Soho.
