Paper Abstract

We have developed a low spectral resolution prism unit for the IRCS at the Subaru Telescope, which covers the wavelength range from 2 μm to 4 μm simultaneously. As the prism has high throughput compared to grism, it is an efficient observing mode for 3-μm water ice band and rapidly time varying objects such as asteroid. We report preliminary results of the performance verifications of the prism unit.
