If the material is lightly soiled, it may be air brushed with a jet of clean dry air
or nitrogen.
DO NOT use Freon.
Sand the Spectralon material under running water1 with a 220-240 grit
waterproof emery cloth until the surface is totally hydrophobic (water beads
and runs off immediately).
Use a flat surface, such a thick, flat piece of glass.
Place the glass into the sink.
Place 220 grade wet sandpaper onto the glass.
Gently move the Spectralon reference in a figure 8 motion on the sandpaper,
using water as needed to wash away the thin layer that is sanded off.
Blow dry with clean air or nitrogen or allow the material to air dry.
If the material requires high resistance to deep UV radiation, the piece should
be prepared as above, then either of the following two treatments performed.
1
Flush the Spectralon piece with >18 m½ distilled, deionized water for 24
hours.
2
Vacuum bake the Spectralon piece at 75° C for a 12 hour period at a
vacuum of 1 Torr or less, then purge the vacuum oven with clean dry air
or nitrogen.
Do not use oils or soaps to clean the Spectralon white
reference.
