Who coats mirrors these days? Stateside. Anyone?
No Newport doesnt - only in hosue work.
No Clausing is too busy - already waiting a year for any response
after multiple emails and phone calls.
No Torus (shouldnt!) - would trust them with a dead cat.
Who coats mirrors?
TIA

Hello Everyone:
James Mulherin at Optical Mechanics.
This thread was braught to my attention this evening. I'd like to
offer a bit more info on our upcoming coating service. First, we're
located in Iowa City IA just of I80 at exit 249. We operate out of
7500 square feet of shop space in the Liberty Industial Complex. We're
been at this location for about 5 years now. In this time we've
delivered over 500 mirrors in the 12.5" to 30" aperture range to
Obsession Telescopes and to many ATMs. We also build fork mounted
Cassegrain Telescopes for Universities and government run
observatories all over the world.
Here's our web address: www.opticalmechanics.com
You can look at test data for a couple hundred of our mirrors on our
web site.
In the past we've use Clausing, Flabeg and Newport Thin Film Labs for
our coatins. We recently took the leap and orderd a coating machine
and will start coating mirrors in-house in August. A little tech info
about the machine: It's an Airco Temescal FCE 4800 with a 48" chamber.
In other words, we can coat mirrors up to about 1.2 meters aperture.
The machine is fully automated with e-beam evaporation, ion assist and
crystal thickness monitoring. It has a 20" cryo-pump for fast
evacuation and a 10" cryp-pum that that operated during processing
when Argon or Oxygen is injected through the ion mill during
processing. I'm flying to Dallas in two weeks to check progress on the
construction and to meet with the coating engineer who will design our
first coating products and program the machine up to run the
processes. At the end of July Dave Pasley (one of our engineers) and I
will return to Dallas for training in the operation of the machine. In
the mean time we are setting up a 1200 square foot clean bay for the
coating operation. The front of the machine will be enclosed by a
class 1000 clean room. This is a stat of the art machine that will
produce very high quality coatings. I'll be happy to answer questions
about our coating producst on this forum.
I have no idea who Mr. Haines is. Never heard of him. I'll call the
guys over at Jim's Instruments and set the record straight. I have no
idea where they got their information.
Regarding phone calls: I'm always available to take them. Our number
is (319) 351-3960. If you get voice mail please leave a message and
I'll call back. You can E-mail me at jcmulherin@opticalmechanics.com.
I check my mail about 50 times a day :-)
Clear Skies!
James

Huh. I thought Torus had their mirrors coated by Flabeg. In any case the
reports I hear of Optical Mechanics mirrors made by James Mulherin are very
good from what I read from the Obsession Telescope yahoo group many of
which are equipped with Torus OMC mirrors.

That issue is well documented around three years ago. Can you cite a single
person who didn't get the issue sorted out.

Looks like you are trying to pass off innuendo as fact. Did those problems
get sorted out? Have there been any over the last two years?

I have not the slightest idea what is fact or fiction at Torus and
I dont care. Keeping track of Torus is a full time job! Who needs
such a job?
I do know for a fact I was told last Tuesday that James Mulherin
no longer is in charge at Torus/Optical Mechanicals/whatever
and that somebody named Haines (sp???) was doing all the optics
there. Who Mr. Haines is I havent the faintest idea. But I was told
this by Jim's Instruments in Iowa City, Iowa who I called for advice
about machine shop work available in the Iowa City area. We were
hooked up with a nice young man who operates out of his house on American
Legion Road which is east of Iowa City and the young man has done us very well
and we are happy.
I further know people have called Torus/Mechanicals/whatever
and nobody answered the phone on five ocassions and email was never returned.
But they evidently do coat mirrors because I was also told by a
the president of Cedar Amateur Astronomers that they are
considering "Torus" to coat their Boller Chivens mirrors in their
large educational observatory complex which they are building.
That is the same club which doesnt even have decent modern working telescope
for members and the public to use! They have
lots of buildings (4 observatories!) and nothing in them but junk.
Hopfully Torus will give them a telescope to use?
Those are the facts I know.

Thirds...just had a 12.5-inch Newt primary done by them...great job,
great service.

The only problem I have with Spectrum is that they don't tell you how
much it will cost to coat the secondary as well! They obviously do coat
secondaries, but their web site does not indicate what the cost is.

Is there a trap somewhere here? I.e. that coating the primary is cheap
but coating the secondary is horribly expensive -- but you surely want
to coat your secondary when you've already coated your primary.....

Probably a northern Iranian conspiracy with Eskimows lurking!
Not to mention the Athabaskan roundabout!!

Thanks. Appreciated and will try them.
With this post Clausing surfaced and quotes us suddenly $250.00! plus
shipping/handling for ..... one 25mm circular mirror. I will
try Spectrum & appreciate the referral.
Thanks,
Fred
