I hear you. Spot TIRs can be ugly, especially with small flat emitters. PM1 might just be the worst scenario. I’ve tried so many TIRs from LEDIL and various AE vendors. The nicest beam so far has been from this one https://www.aliexpress.com/item/32367183046.html. It’s a SOB to remove from the holder, though.
These https://www.aliexpress.com/item/1005002280736440.html might just be a perfect fit. I have them on order in 10° smooth and pebbled. Hoping the pebbled will still hit 15kcd or more with a slightly softer beam or that the smooth can be focused such that the secondary projection of the emitter can be hidden within the hotspot.
Also in that order where these https://www.aliexpress.com/item/764917590.html in the ‘center sand’ format. They won’t fit as nicely I don’t think but will probably have the beam I desire.
