DESCRIPTION: Please perform acceptance testing of PN.Spectrograph optics as agreed with Dr K Taylor (AAO). This includes measures of thickness, diameter, radii and surface quality for both surfaces of all 17 lenses and interferometer sphericity measures of all except the long-radius surfaces (second surface of CM2). In addition, the decentering of each surface in x and y directions and corresponding wedge angles should be measured (the orientation chosen for x and y is arbitrary for each lens but should be marked on the edge).

AGREED COST: $A 11,800

PLEASE INVOICE (unless otherwise advised):
