id3c.devices.laser_optics#

Laser optics bundle (us / ds axes) with IN/OUT state.

The us and ds axes are upstream and downstream positioners of the laser optics. At nominal positions they are either fully IN (in the beam path) or fully OUT (retracted).

This device declares its two axes as InterlockedEpicsMotor. The actual interlock callable (against sample_stage.omega) is wired late, in id3c.startup.

Configuration Components (plain ophyd.Signal, kind="config"):

in_position – nominal IN location (mm), applied to both axes
out_position – nominal OUT location (mm), applied to both axes
tolerance – +/- window (mm) for IN/OUT comparison
settle_time – post-move delay (s) in move_in/move_out

Derived Components (ophyd.signal.AttributeSignal, kind="omitted"):

out_status – mirrors is_out

Derived signals are subscribable, which is what the mid-motion interlock watcher on sample_stage.omega uses. Note however that AttributeSignal itself does not emit on EPICS updates; the watcher should subscribe to the underlying us.user_readback and ds.user_readback signals (which it does, by wiring in startup.py). out_status is exposed for manual .get() queries and for any code that just wants the boolean.
