That may be true-- correct me if I have this wrong.. & remember
Alan is all new to this in spite of what he put in his "about me"
-- These cubes (or kubes) are RGB or X-cubes. NOT actually PBS- (Alan is changing that) PBS cubes come in at least 3 wavelengths --this for combing two reds. a blue & a 405--a 520 and a 532 BUT not so good for making magenta- yellow- teal - or a great 'white'- look at the PBS cubes at Opt ... R -G B..
afaik Alan can get the PBS- the few we found for combo 44s are PBS cubes for 450nm high power..
-CONDITION-- again I am no optics expert-- BUT visually- with a loupe- on the two 18mm ones I already have the edges , the corners and all surfaces look-- to me anyway-- flawless. & they are indeed polished on the bottom & top. IMO that makes better pics when done from above.. the frosted glass look is not there.
the 25mm ones are not 6 sides polished BUT I had to jump on the BIN --less than $6 -- even with some chips etc- that is a cheap prism.. 'Very Slight' is a 'grade' of cubes that did not pass QC. its IMHO same as 'near=perfect' .
Certainly good enough for me..
(pss don't tell anyone --Ok)
for me anyway shipping to Texas has been around 12 to 14 days. overpacked - had to break out the box cutter-- one thing about that overkill packing-- it leaves a good impression.. and 'could' make the package look a little TOO hard to open- inspect- and reclose.. who knows.. but both came double boxed like that.. I would rather get stuff like that than a single thin ass bubble envelope with very little protection..
any help- tips etc- fatherly advise-- whatever-- watch his back.. good person.. new to forums too... so --thanx
XXXXXXXXXX combining posts- move along... nothing to see here!!

pardon the double--will edit later-
after re-reading all that.. I am thinking (and no real reason I have not just shot 3 pointers thu one here- take pic.. sry-- I will on sunday promise..)
what may be more correct.. his X Kubes (so far) would not be the kind one uses to combine same or near same nm.. those would be PBS ..right? I know a white LED light nicely splits the colors down to RGB. so stands to reason a RGB sled would have its RG & B split.. or putting R-G and B lasers into the right three sides would make a 'white' . almost 4am-whew long day..
CYA
new 488/60 arrived today (love it)- just in time for new prism/X-Kube pics.
I think I can get 488 from my argon. (ML)- not sure of the exact nm from SL Argons,,need to get ALL my 'Blue Family ' out for a new group pic
