Is the second focus of an
ellipsoidal reflector before or after the
gate? Why does it matter?--Later in your article you talk briefly about shutters working opposite, and having to insert a
gobo upside-down and backwards, but don't explain the reason.
I don't mind comments, ...
Well then, since you opened the door...
On the
Fresnel page, you state "A
Fresnel uses a
spherical reflector, and thus it produces a circle of light." implying a causality that doesn't necessarily exist.
"the
LCL (lamp center length, described in a future article on lamps)" wrong acronym
On to Part 3 -
ERS :
"and the heat sinks that remove the heat from the light beam,"
"The absolute best feature of this
unit is the
aspheric lens that makes the
shutter cuts appear perfectly square (a problem on all other
ERS units is that their shutters appear
wedge shaped when you push them in). " See
pin cushion.
I'd avoid using the term "
lens train" altogether, using instead
lens tube or
lens barrel as applicable.
" For glass gobos (called lithos " Not all glass gobos are, or are called, "lithos." LithoPatterns® is a HES copyright.
"There is the
base, and then there is the
barrel. The
base houses the lamp,
reflector, cap,
shutter, and
gobo slide." Since
base has a pre-defined meaning, I'd use "body" instead.
"Because of a unique characteristic of ellipses, there are two focal points." I've argued this before, to no avail: Lenses have focal points, reflectors have foci, plural of focus(es).
"Now, while all
ERS units are technically the same size, " I don't know what this means, but I'm pretty sure I disagree.
"but the
Selecon Pacific mounts its lamp radially (see below). Because of the radial mounting of the
lens, the
Pacific is much more efficient about venting heat"
Pacific IS NOT a radial
fixture, and I think you mean "lamp" rather than "
lens."

Here's an idea (for everyone, not just Esoteric), [that may need some more cultivating]: Next time you write an article, copy it into a post on
ControlBooth, click Go Advanced,
Preview Post, and pay attention to the words that are highlighted by the
wiki auto'bot. Make sure your use of the word is congruent with the
wiki's. If not, either you've used the wrong term or the
wiki is wrong. I'm not about to state that our
wiki is, or will ever be, 100% accurate, but seeing as how its articles are edited and watched by industry veterans, it may be the most authoritative source.
You then can just cancel out of the post without actually posting. Note that the
wiki will only flag a term the first time it's used, so you may need to copy/check a paragraph at a time. Note also the the 'bot only catches the singular form of terms (we're working on a way to flag plurals in the next upgrade).
What does everyone think of this idea? Cheating? You use spell and grammar check, don't you? Why not a glossary/"jargon" check?
