1-5 Micron Camera

 

 

NSFCAM2 is a 1-5 micron camera, built at the Institute for Astronomy, (IfA), for the NASA Infrared Telescope Facility (IRTF). The camera uses a 2048x2048 Hawaii 2RG detector array. The image scale is 0.04 arcsec/pixel and the field of view is 80x80 arcsec. It contains two filter wheels. The first is a 28-position wheel containing broad-band and narrow-band filters, and a wire-grid polarizer. The second contains a 1.5-5 micron CVF and grisms. for low-resolution spectroscopy. A third wheel, located at the F/38 telescope focal plane inside the camera, contains grism slits and field lenses. (The field lenses will allow NSFCAM2 to be used with the AO system when it is finished.) An external wheel containing a waveplate can be used with a polarizer in the CVF wheel for polarimetry.

 

NSFCAM2 was funded by NSF and the Hawaii-2RG array was provided by Don Hall courtesy of his work for JWST.
