Design#

ZShooter has two fixed-format spectrometers, each with three spectral channels:

VIS: B/G/R, each with one 2k × 4k qCCD.
NIR: YJ/H/K, each with one 2k × 2k LmAPD.
ZImager: three additional qCMOS detectors for simultaneous optical imaging.

The spectrometers use six single-detector focal planes, with no detector or grating mosaics. ZFront, ZImager, ZSpec VIS, and ZSpec NIR are separately supported assemblies for independent alignment and removal.

Optical Design#

ZShooter’s optics are fed both by K1 M2 and, eventually K1 DM2. The front-end must support calibration light sources, co-registration of ZImager and ZSpec, seeing-enhancement from future AO, and neighboring L and R RNAS instruments. The current design has been updated incorporating conceptual review feedback, with the main architectural change a move from three to two spectrometers, each split into three science channels.
