Q: Are Optional Ribbon Cable (ASM00362) and Optinoal 2-PIN Secondary Cable (ASM00364) delivered with the product? Or, Do we have to order them separately?
A: Optional Ribbon Cable and Optional 2-pin Secondary cable for working with tubes are delivered separatly upon customer's request.
Q: What's the difference between your
PBF02A and PBS02A ?
A: PBF02A is 3 waves/inch
flat and is 1.6+/-0.1mm thick.
PBS02A is not optically flat and is 0.7+/-0.07mm thick. The
flatness of the PBF allows it to be used as a fine optical component.
The PBF can be used with confidence in the imaging path without
any distortion.
Q: What is the difference between the
PBS series (PBS and PBF) and the PPL series?
A: PBS02A and PBF02A
are both optimized for AOI=45 degree, and PPL is optimized for AOI
close to 0 degree.
Q: What's the smallest size your PBF/PBS/PPL
can be cut into? What's the tolerance?
A: 7x7mm is the
smallest size with a tolerance of +/-0.2mm for both the X and
Y directions.
Q: Do you offer only 1.6 mm thickness
for PBF02A?
A: Yes
Q: Can the flatness be better than 3
waves/inch?
A: Yes, but it becomes
much more expensive, since it would be a non-standard part. We
have found that 3waves/inch achieves a nice balance between cost and
performance.
Q: On one of Moxtek presentation files,
you say PBF/PBS/PPL works well under “moderate light level ".
What does "moderate"
mean?
A: Only the PBF
needs to be operated in "moderate light levels." "Moderate
light levels" basically mean the light level that will maintain
the flatness of the PBF and will not cause a distortion in the
image because of thermal expansion. There have been no problems,
however in any applications so far with thermal expansion induced distortion.
Q: On the same file, a Moxtek PBF (with
another PPL as pre polarizer) shows 10000:1 contrast when working with
mirror/QWP combination instead of with LCOS panel. Is there any type
of analyzer you applied? (I don't see anyone on the drawing)
A: Here's the short
answer - We originally did this with a customer and the analyzer
was the PBS, however to obtain high levels of contrast we do recommend
using some type of analyzer.
Q: If the above statement is true, then
it means in reflection mode, PBF features around 20:1 contrast. Then
the contrast of reflected light twisted by QWP can become 10000:1.after
passing through the PBF, with no analyzer. Is this right?
A: No, it is necessary
to analyze the reflected image.
Q: When will PBF move to MP phase?
A: We need 60-90
days lead time for volume orders of PBF. This is necessary for
ordering the PBF substrates.
Q: What's the lead-time if I want to
order some ( 20 to 100 ) Moxtek samples ?
A: 12-16 business
days.
Q: What's the lead-time of MP pieces?
A: Same as above.
Q: If the quantity is huge, is it a must
that we deal with you through such a complex hierarchy? (Moxtek --> Polatechno
-->
Taiwan Nippon Kayaku Co.)
A: Yes. We
have had customers in production in Taiwan and it is not as confusing
as it seems.
Q: Can we customize the AR coating (or
other types of diachronic coating) spec we want? Or is it possible
for you to cooperate with coating houses we assign?
A: Anything is possible. However,
anything that is non-standard will be more expensive. It is possible
to work with other coating houses, but it is easier for us to work
with companies in the US.
Q: Does the cost relate to the thickness
(0.7 mm or 1.6 mm)?
A: Partially.
The thick flat substrate is substantially
more than the 0.7mm substrate for several reasons (the biggest
reason is the thick substrate is polished).
Q: What are the definitions of, and differences
between optical grade 0/1/2/4? Is grade 1 good enough for imaging area
application?
A: The difference
is the size of the defects. The defect size ranges from
1mm for optical grade 4 and 150 microns for optical
grade 0. It depends on how close the parts are to the image plane.
Q: Any recommendation on the most optimized
cutting size from cost viewpoint?
A: The smaller the
better, but leave at least 1-2mm edge exclusion around the part.
Q: Please help to fill in attached cost
due diligence table, based on normal AR coating requirements.
