Abstract

The wavelength range of the General Electric spectrophotometer can be extended into the near-ultraviolet spectral region. The cam-rod extension technique usually employed for infrared work is not applicable in the ultraviolet region. An accessory consisting of two glass wedges can be used to give both ultraviolet and infrared extensions. Details of the accessory and results obtained by its use are described.
