Sure does looks pretty and sharp.
Yeah, you are supposed to use a syringe and fill the ferrule hole with epoxy until it comes out the other end and then insert the fiber. I didn't have a syringe so I simply dipped the fiber in epoxy and then inserted it into the ferrule. You should also make sure that there is a drop of epoxy about the size of the fiber on the tip of the ferrule. I used a 100um or so piano wire I recently bought to apply a tiny bit of epoxy to the ferrule's end. The idea is that once the epoxy cured, you cleave it just above the tip of the ferrule and then polish using 5um or so polishing film until the epoxy almost disappear from the ferrule and then finish it off with finishing polishing film until it's gone completely.
Are you talking about this collimator? https://www.thorlabs.com/thorproduct.cfm?partnumber=F240FC-980
If so, yes I used it already but with questionable terminated connector as mentioned above. It works well, but beam diameter is kind of big at almost 2mm. Still waiting for epoxy on the new connector to cure before I can try polishing it. Not sure if I would be able to tell if works any better with a properly terminated and polished fiber or not without using a laser meter.
