I have searched high and low and can not find a tir optic supplier with a selection of optics smaller than 20mm.
I just fitted a Nichia 219 in my EagleTac D25a but the reflector had to be hacked up to get the focus close and because I couldnt find a supplier of Nichias on 15mm boards.
So, to fix my bad focus and possible short across the leads, I am looking for a TIR optic that has a diameter of 15mm and a height of 9mm.
Or, if a 20mm x 10mm optic from carclo can be modified to fit, please let me know.
