Abstract

The design and construction of an induced-transmission interference-filter array for use in multiwavelength pyrometry are described. The array which covers the 0.75–1.70-μm wavelength range is shown to be both an efficient beam splitter and wavelength selector. Fabrication details of the filters are provided with a complete description of the pyrometer system.
