  We describe the infrastructure being developed to align and characterize the
detectors for the Subaru Measurement of Images and Redshifts (SuMIRe) Prime
Focus Spectrograph (PFS). PFS will employ four three-channel spectrographs with
an operating wavelength range of 3800 $\AA$ to 12600 $\AA$. Each spectrograph
will be comprised of two visible channels and one near infrared (NIR) channel,
where each channel will use a separate Schmidt camera to image the captured
spectra onto their respective detectors. In the visible channels, Hamamatsu 2k
x 4k CCDs will be mounted in pairs to create a single 4k x 4k detector, while
the NIR channel will use a single Teledyne 4k x 4k H4RG HgCdTe device.
