    Abstract: A method is provided for characterizing the peg region of a near-field transducer incorporated into a write head of a HAMR magnetic recorder. The method includes providing excitation radiation to one or more near-field transducers. The near-field transducers include an enlarged disk region and a peg region at least partially in contact with the enlarged disk region. The method further includes filtering output radiation from the near-field transducers by passing a portion of photoluminescent radiation emitted by the near-field transducers in response to the excitation radiation and substantially blocking the excitation radiation transmitted by the near-field transducers. The method also includes detecting the portion of photoluminescent radiation and characterizing the peg region of at least one of the plurality of near-field transducers.
