Abstract

We constructed a near IR camera PICNIC equipped with the 2D array detector NICMOS-3 manufactured by Rockwell. Employing a four aspherical metal mirror system for reimaging optics, PICNIC is an IR imager distinguished with high throughput and small chromatic aberration. In addition to normal imaging mode, the camera has a prism spectroscopy mode and a polarimetry mode. A direct view prism, which can be optionally inserted in front of the camera, make it possible to obtain multiobject low resolution spectroscopy in the wavelength range from 1 to 2.5 micrometers at resolving power of approximately 50. Linear polarization can be measured with combination of the filters and/or the prism. We realized user-friendly operating environment as well as automated observation.
