  We analyze spectropolarimetric observations of the chromospheric Ca II 8542
line taken by the Interferometric Bidimensional Spectrometer (IBIS) at the Dunn
Solar Telescope and photospheric Fe I 6302 lines obtained with the Solar
Optical Telescope (SOT) of Spectro-polarimeter (SP) on board the Hinode
satellite. The data were obtained on 2012 January 29 targeting NOAA active
region (AR) 11408 and AR 11410. By using the center-of-gravity (COG) method we
compute the line-of-sight (LOS) field strength for observed lines of Fe I
6301.5/6302.5 with SP spacecraft at every places in the active region. Also, we
construct a COG map for the chromospheric IBIS data of Ca II 8542 line in
comparison with COG maps derived from the SP of field strength. We found the
photospheric field strength ranges up to 2 kG in plages and up to 2 kG or
higher values inside the umbral region. In the case of chromospheric field
strength, the LOS field inside the umbral region increases up to 800 G, and the
field strength decreases toward the edges of sunspot.
