SCIP is a slit-based spectropolarimeter developed for the third flight of the Sunrise balloon-borne solar telescope. In a "normal mode", it simultaneously measures full Stokes IQUV profiles for multiple spectral lines in near-infrared wavelength ranges around 770 nm and 850 nm. These ranges include photospheric Fe I 846.8 nm, upper-photospheric K I 766.5 nm and 769.9 nm, and Ca II 849.8 nm and 854.2 nm. These lines are sensitive to the Zeeman effect, enabling magnetic-field measurements from the photosphere to the chromosphere. Thanks to the 1 m aperture telescope and the greatly reduced influence of atmospheric seeing at balloon altitude, SCIP measures these lines with spatial and spectral resolutions of 0.21" and 1×10⁵, respectively. These are enabled by corresponding samplings of 0.094" and 2×10⁵. Considering the telescope and instrument throughput, SCIP achieves a polarization sensitivity of 0.1% (1σ) with a 1 s integration time at each slit position. It can reach 0.03% (1σ) with a 10 sec integration and 2 pixel binning along the slit in the 850 nm band, whereas no binning is needed in the 770 nm band. SCIP has a "rapid mode", in which Stokes I spectral profiles are obtained without polarimetric measurements. The FoV is 58" (along the slit) × 58" (scanning), and the scanning range is adjustable depending on the science targets.

SCIP provides a slit-jaw image of the 770.5 nm continuum with a FoV of 60" × 60".
