摘要:

我们描述的基础设施正在开发的斯巴鲁测量图像和红移(SuMIRe)的主要焦点光谱仪(PFS)的检测器对齐和表征。PFS将采用四台三通道光谱仪,工作波长范围为3800 $Å$至12600 $Å$。每个光谱仪将由两个可见光通道和一个近红外(NIR)通道组成,其中每个通道将使用单独的施密特相机将捕获的光谱成像到各自的探测器上。在可见光通道中,Hamamatsu 2k x 4k CCD将成对安装,以创建单个4k x 4k探测器,而NIR通道将使用单个Teledyne 4k x 4k H4RG HgCdTe设备。

英文摘要:

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 $Å$ to 12600 $Å$. 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.
