Need help on collimator lens

[AgentKellerman]

So the first time I ordered from tcss I ordered one of eatch of the Collimator lenses so I could try itch one out, so the ine I settled with was compleley flat on top and gives a very tight beam, and has a tight diamond shaped beam when pointing it at things,can someone help me identify which lens I am using because I want to get more, I ordered some 5 deg lenses but I don't think they are the same, they are not smooth on the face of the lens they have divot grooved out

[cardcollector]

The smooth top is the ten degree

[AgentKellerman]

Ok cool, so how do I tell the diff between the 5 deg lens and the lux rebel 8.7 degree

[cardcollector]

I don't know as I have never used the rebel lenses.

sorry.

The Rebel 8.7 degree lens should have a taller tab on it.
