Abstract
A method for fabricating an optical device that uses a robust purified adhesive as a bonding agent is disclosed. Impurity particles greater than or equal to 0.1 microns are removed from liquid precursor materials prior to polymerization or cross-linking. The impurity particles are separated from the precursor by applying a high gravitational centrifugal force. The purified adhesive is used to bond together optical components disposed in the optical path of the device. The purified adhesive resists damage from high-powered lasers because impurity particles that would otherwise absorb and scatter laser light are removed from the adhesive.

Describe in detail
The invention discloses a kind of polymerization or crosslinked before from liquid polymer precursor, remove impurity particle method. Should Method comprises makes precursor liquids rotate predetermined time under predetermined speed in high gravity centrifuge, required to realize Particle separation. The polymer that makes from the precursor that obtains with this centrifugation technique purifying can tolerate high-power laser pulse and The damage of its instantaneous value. This is to remove about 0.1 micron and bigger impurity particle reality by separating from precursor material Existing.
