The probe base is covered either with a 300-µm-thick silicon spacer (8.5  3.9 mm) or aluminum metal
cap (7.3  4.8 mm) with dedicated dovetail structures (Figure 6). Both probe covers serve primarily as
10
light-shields for the light-sensitive circuits in the probe base but also enable alignment and attachment
of compatible stereotactic insertion drives developed amongst others at HHMI Janelia Research
Campus.
10 Probes with metal cap are available as of June 2019.
