The FLI PDF focuser uses three long cone point setscrews to connect to this adapter's V-groove. The PDF has a 4.1-inch diameter, 1/4" deep pocket which this mount fits into. This mount presents the OPTEC-3600 dovetail for attachment of any device with an OPTEC-3600 receiver.
A word of caution however, the stepper motor on the PDF is mounted very close to the pocket and protrudes almost 0.6" above the PDF body. This adapter has been demonstrated to work with Optec's #17481 3" Receiver Tube for the NGC316 telecompressor.
