Hector is a multi-integral-field-unit instrument for the Anglo-Australian Telescope, providing simultaneous feed to two spectrographs. The Spector spectrograph, with its unique all refractive 2-arm design, delivers fixed resolution and high resolution in the blue end. The mechanical assembly of Spector overcomes tight spacing and tolerance constraints. This paper presents a detail overview of the opto-mechanical component design and specifications of Spector, which was completed and achieved first light in December 2021.
Hector is a multi-integral-field-unit instrument for the Anglo-Australian Telescope (AAT). It simultaneously feeds two spectrographs, the existing AAOmega spectrograph and the new higher-resolution Spector spectrograph. Both are fed with new generation hexabundles. Spector has an all refractive 2-arm design which delivers 1.3A fixed resolution across the full wavelength range has higher resolution in the blue end and R=5000 in the red which makes Spector uniquely powerful spectrograph. The mechanical assembly of the spectrograph is designed to provide specific solutions to the tight spacing between component assemblies with strict tolerance constraints which makes Spector an interesting challenging instrument. The components start with a custom slit assembly providing precise positioning of 855 fibres which forms the interface point for light injection to the spectrograph. This paper presents a detail overview of opto-mechanical component design of Spector spectrograph along with technical specifications. Component fabrication, assembly, testing alignment was completed by early 2021 and received first light in December 2021.
