Research Abstract

We have carried out a prototype development of a integral field unit for an infrared multi-object spectrograph SWIMS, which is being built for a 6.5m telescope of the University of Tokyo Atacama Observatory project.
An optical solution is successfully obtained, which divides the field of view of 14 arcsec x 10 arcsec into 26 slitlets with 0.4 arcsec width. The solution fits in a compact dimension of 170mm x 220mm x 60mm, which is the limit to be stored in the MOS-slit-mask storage.
To achieve the required final spot, we have to incorporate non-spherical surfaces. We then carried out a study to fabricate such surfaces using extremely-high precision machining, and confirm that such surface can be fabricated with required surface roughness.
