NOA-63

It is recommended for the bonding of achromats, prisms and all other precision compound optics.
The outstanding characteristics of the adhesive are its low fluorescence and its excellent transmission
in the near UV range. After full cure, the adhesive has good transmission from 320 to 3,000 nanometers.

NOA 63 is cured by ultraviolet light with maximum absorption in the range of 350 to 380 nanometers. The NOA bond can be separated in chlorinated solvent such as methylene chloride. The bonded area must be soaked in the solvent and normally will separate overnight if only procured.
