Golden Gate - Realignment of a ATR Accessory


The ZnSe or KRS-5 lenses of a Golden Gate ATR Accessory focus the beam of a light signal to pass through the small aperture of the diamond crystal assembly. As such a correctly aligned beam of light has to arrive at the lens before the beam is focussed to pass through the diamond crystal. If there is no registered signal whilst in a spectrometer system, even though a ZnSe or KRS-5 lens assembly has been replaced after it has been removed, alignment of the mirrors in the optical unit will need to checked.
