There seems to be no good way to search for TIR's, just search at each individual supplier for TIR and look threw the tons of results... Maybe I'll get a list together here like there is a list of hosts.
Anyway for now I'm looking for an 18mm TIR for an XM-L that is as short as possible, I found some crazy looking Ledil TIR's that are 18mm wide and only ~4.5mm tall but they're for Luxeon LED's only :(
Can anyone point me to some different XM-L options in 18mm, I can make any height work but the shorter the better so I can cut the body down some to better match my S6 EDC host (the lens is for my D10 and I want them to match), looking for medium - flood optics however if only spot type is available Ill take it.
That’s what I’ve done now, just looking for other options. I forgot the exact PN but this is a wide 20mm carlco I’ve sanded down in my spare D10 stripped head.
An optics thread would be a good idea. I start with a search of my favorite manufactures sites: Ledil, Carclo, Khathod, etc, then look to see if anyone has them. Future electronics in Canada has had some odd ones. Cutter in Australia, Digikey and Mouser in the US. DX, Intl Otdr, CNQG, FastTech, and KD don’t list them by manufacturer(probably knockoffs) only by size and often with incomplete data. It would be excellent to have it organized so that those of us who have ordered them can help fill in the missing info. Pictures of TIR optics are often unhelpful.
You can widen the center bore with a countersink bit then repolish with a Dremel tip.
The Carclo single-LED TIRs have an incredibly ugly beam pattern. All of them I've tried project a square pattern in the center. Truly not nice to look at. The cheap unknown-brand 20mm 10* TIRs (from IOS, FT, probably others) with the white plastic holder give a lovely artifact-free beam, why can't Carclo get theirs to do the same?
My experience with cutting the 3-up TIRs down from 20 to ~17mm shows even that kind of abuse doesn't affect the beam. I haven't tried doing the same with the 10* generic TIR but I have no reason to suspect it would react badly if cut down to a smaller OD.
