WHITE LIGHT Page
The WHITE LIGHT feature is used to facilitate alignment of optical accessories
in the sample compartment.
When the INITIALISE function key is pressed the instrument will align the
grating so that the zero order diffraction passes through the sample
compartment. This provides a beam of white light which can be seen when a
white card or similar is placed in the light path.
When alignment is completed, pressing the STOP function key returns the
grating to its normal position and pressing the SETUP PAGE function key
returns to the Setup Page.
