We old-timers remember CVI as C VI Laser (pronounced Csix) an
independant company specializing
in optical components, YAG lasers, and later spectrometers. If I
remember correctly
it reffers to column 6 of the periodic table, the axis around which
all the infrared materials
reflect. (Si, Ge, ZnSe, CdTe, InSb, etc. Yu Hahn was the founder and
Bob Pixton was their
laser guy.

Sorry about the spelling, I really need to read these things before I
post!

This may not be correct, but in the 70s, we interviewed an employee of CVI,
and we were told CVI was Roman Numeral for 106, meaning the wavelength that
they specialized at the time. Of course, memory is fading now, so I don't
remember if it stood for 1.06 or 10.6 microns, or if it was left
deliberately ambiguous, in order to cover both.

I admit to being easily confused, however I know II-VI very well (too
well!),
being a former crystal grower, and I didn't make this mistake.

Not sure what you mean - they still do coatings, but restrict
themselves to UV/vis/NIR wavelengths and materials. Not sure if
they're doing anything in the 2-5um kind of wavelength range.
Particularly in the IR I consider coating to be an integral part of
making optical components - companies who only polish parts are only
doing half the job.

OK, but as per other replies the CVI name doesn't refer to columns of
the periodic chart.
While it doesn't seem to have hurt them, I've always thought the II-VI
name was a problem.  First where do you put it alphabetical listings,
under I or T?  I can't even begin to count the number of times I've
seen it written II-IV, and if you leave off the hyphen you could read
that as III-V, which was the name of a completely different company
(Three Five Systems).  At the time II-VI aquired some of their UV/Vis/
NIR subsidiaries I suggested that following the original naming logic,
given the expanded range of materials being grown and used the company
name be changed to I-II-III-IV-V-VI.  This suggestion was not greeted
with enthusiasm.- Hide quoted text -

as a current CVI Melles Griot employee, I can confirm that CVI stands
for Roman numeral 106.  When founded, CVI did mostly Nd:YAG coatings,
so it does refer to the 1064 nm, or 1.064 µm wavelength.  As
previously pointed out, to be consistent with this idea, that would
mean you need units of 10nm, i.e 106 10nm, or, units of 100µm, i.e.
1.064 100µm, which IMO makes absolutley no sense.  There are no such
units.  If the founders really wanted to echo their favorite
wavelength in nm, then their name should have been MLXIV, but I
presume this acronym was simply too awkward as a company name.

As to the name Melles Griot, everyone knows that that is a derivative
of the diner down the road here, where the engineers can enjoy the
world famous Beamsplitter Burger.  This is of course not true, but
it's what we tell anyone who can't understand the name on the phone.
