P2.7 Looking for filter defects/effects/features

• Phase : 2
• Status : Draft
• Category : Daytime testing (functionality and operability) (C2)
• Recurrence : once at commissioning
• Duration : 1 hour(s)

Description

• Finding the filter defects/effects/features using different lamps within the instrument.
• If required, this may be repeated for on-axis source from RR for selected or all filters while the AO loop is running (daytime)

Prerequisites

• If relevant, estimate and remove the NCPA using phase-diversity method.
• RR mounted on SX side.

Procedure

• Take the images of all the filters using different lamps within the instrument to locate/find out the filter effects/defects/features.
• You may take short- and long-exposures to get better contrast of the features if required.
• This may be repeated with the on-axis source from the RR with AO running to check for any extra features arriving from outside SHARK-NIR but from LBT mirrors or the deployable arm.

Success criteria

• All the filter images saved.

Notes LBTO support

• Support from LBTI/LBTO?
