摘要

A new advanced high resolution spectrograph has been developed by Kiwistar Optics of Industrial ResearchLtd., New Zealand. The instrument, KiwiSpec R4-100, is bench-mounted, bre-fed, compact (0.75m by 1.5mfootprint), and is well-suited for small to medium-sized telescopes. The instrument makes use of several advancedconcepts in high resolution spectrograph design. The basic design follows the classical white pupil concept inan asymmetric implementation and employs an R4 echelle grating illuminated by a 100mm diameter collimatedbeam for primary dispersion. A volume phase holographic grating (VPH) based grism is used for cross-dispersion.The design also allows for up to four camera and detector channels to allow for extended wavelength coverage athigh eciency. A single channel prototype of the instrument has been built and successfully tested with a 1mtelescope. Targets included various spectrophotometric standard stars and several radial velocity standard starsto measure the instrument's light throughput and radial velocity capabilities. The prototype uses a 725 lines/mmVPH grism, an off-the-shelf camera objective, and a 2k×2k CCD. As such, it covers the wavelength range from420nm to 660nm and has a resolving power of R ≈ 40,000. Spectrophotometric and precision radial velocityresults from the on-sky testing period will be reported, as well as results of laboratory-based measurements. Theoptical design of KiwiSpec, and the various multi-channel design options, will be presented elsewhere in theseproceedings.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
