Helen Munter is informing Colleen Aflak that she will receive a Spot Award of $500 on July 15th in recognition of her contributions to making the San Mateo office relocation easier for the team. The PCAOB established Spot Awards as part of its Total Rewards program to provide special recognition to employees whose achievements are exemplary and help achieve office, division, and Board goals. Colleen was nominated for this award by Emily Kwong for her work assisting with the office transition.
The document discusses the author's plans for semi-retirement that did not materialize, leading them to continue working instead. They also mention developing coping strategies like leaving notes to address some memory problems that have arisen with age. The author aims to keep an open mind, try new technologies, and avoid mistakes in their lens design work.
The document discusses the office's plans for relaxing over the summer break. It mentions that the employees will lighten their schedules, have some fun activities like office pillow fights, and ease up on their heavy workloads from the year. They recommend taking a break to stay healthy and not losing perspective from too much work. The plans for summer include relaxing at home by reading, listening to music, taking a trip, and taking it easy with quiet times at home.
A new baby is being born, making the recipients grandparents. They are excited by the big news of a new addition to the family. Babies grow quickly so they should prepare to help with care which can be tiring, and the grandfather should get his camera ready to capture pictures of the new baby as it grows. The family is congratulated on the new baby.
What does the future look like? Is it a dark space where we’re suffering from varying degrees of techamphetamine or are we heading towards a Utopian fantasy of abundance and harmony?
Understanding that our basic human needs and wants barely change, we explore the future state of a range of topics; from our need for physical sustenance through to our age-long fascination of transcending the limitations of our biology.
Looking at the future from a human perspective, our potential for greatness is teetering on a fine line between darkness and hope. We’re banking on the latter.

Aberration theory - A spectrum of design techniques for the perplexed - 1986.pdfDave Shafer
This document summarizes the design process for a Double-Gauss lens using aberration theory. It begins with the historical basis of two Gauss doublets back-to-back, then walks through building up a design from first principles using aberration theory. Key steps include: 1) Adding concentric surfaces to cancel astigmatism; 2) Adding an aplanatic/aplanatic shell to introduce Petzval curvature; 3) Adding a concentric/concentric shell to push the system to a telecentric exit pupil. This allows removing the final lens element far from the image. The result is a corrected Double-Gauss design arrived at through theoretical understanding rather than trial-and-error optimization.
The document discusses how early lens design progress was hindered by slow hand calculations and lack of modern materials. It provides examples of simple lens designs that were possible even pre-computer but had limited applications without modern technologies. The document emphasizes that while computers have advanced design capabilities, fundamental design ideas and theories are more important. It provides several examples of innovative lens designs the author developed through conceptual thinking alone. The document cautions against overuse of new technologies like freeform surfaces and metasurfaces without consideration of conventional design alternatives.
1) Snakes played an important religious role in ancient Egypt and were depicted widely in art and iconography. When Moses was in Egypt, snake imagery would have been everywhere.
2) Some scholars propose that the Levite tribe, including Moses and Aaron, may have originated as Egyptian priests who followed Moses out of Egypt and had connections to snake handling and worship. References to snakes in the Bible may relate to this.
3) In the Bible, Moses was instructed by God to make a copper snake idol to cure snakebites, contradicting idol worship bans. This later developed into a snake cult in Jerusalem until being destroyed centuries later. Ancient Near Eastern snake cults and worship were common.
1) Optical design techniques include investigating multiple versions of simple designs to find the best one, as different versions can have tradeoffs in higher-order aberrations.
2) Stop shift theory is a useful technique for creating new designs by finding aperture stop positions that correct specific aberrations, such as lateral color, even if the final stop position is constrained.
3) Combining simple optical systems with useful properties, such as common axial color cancellation, is a way to develop new complex corrected designs like the CMO (catadioptric, mirror, objective) type.
Georgia O'Keeffe was an American artist known for her paintings of flowers, landscapes, and cityscapes. She pioneered abstract painting in the early 20th century, creating non-representational works using only shapes, colors, and forms as early as 1915. Her early abstract paintings were prominently displayed by her husband Arthur Stieglitz at his 291 gallery, exposing the American public to this new style of art. O'Keeffe was influenced by Arthur Wesley Dow's principles of composition and abstraction, and she credited Arthur Dove as having the most significant impact on her development as a young artist moving her style towards abstraction.
Frederic Mistral wrote a long love poem called "Mireille" about his native region of Provence, describing its traditions, culture, and dialects. Charles Gounod later adapted this poem into his 1864 opera of the same name. While Gounod's opera "Faust" has been performed thousands of times, his "Mireille" set in Provence is now rarely performed. The opera showcases aspects of Provençal culture described in Mistral's poem, such as the folk dance called the Farandole, and beliefs in witches and sylphs.
Cooke triplet lens with freeform surfacesDave Shafer
The document discusses optimizing a Cooke Triplet lens design for a strip field using freeform surfaces. It finds that with 10th order conventional aspherics on all surfaces, the design can be diffraction-limited over a 20 degree field at f/2.5. Replacing the aspherics with 10th order freeform surfaces and optimizing for a 20x1.5 degree strip field improves performance tenfold to a wavefront of 0.0040 waves rms. Narrowing the strip field to 20x0.5 degrees further improves performance to 0.0025 waves rms, showing the benefits of freeform surfaces for strip field designs.
Modified freeform offner, august 11, 2021Dave Shafer
An Offner 1.0X relay system can be given a greatly increased field size with good aberration correction by adding to the design two 45 degree flat fold mirrors that are given some freeform aspheric deformation.
A freeform aspheric version of the classic Dyson design gives much improved aberration correction and makes for designs that are fast speed and have a large field size, especially large rectangular strip fields
A wide angle fast speed unobscured freeform aspheric mirror design for the IR is shown to be enormous in size compared to an all refractive 3 element lens of germanium with conventional aspherics and better performance.
Schiefspiegler telescope with corrector lensesDave Shafer
This document contains contact information for David Shafer of David Shafer Optical Design and describes an unobscured 6 inch aperture f/10 telescope design from 1990. The design uses BK7 lenses and spherical mirrors to produce a diffraction limited image over a 1 degree flat field with no tilt at f/10 and has a length approximately equal to the focal length. It also references a simplified version of the design from a slideshare presentation that has a shorter length of half the focal length using tilted lenses and spherical mirrors with an optional fold flat.
A survey of some interesting Gregorian telescope designs includes some with all spherical surfaces as well as some with a 20 meter spherical f/1.0 primary mirror and sub-aperture corrector mirrors.

1. Now that this
4th annual
April Fools
edition of the
Focus has gone
to press, your
hard-working
editor can relax
a little. Watch
some TV, catch
up on my read-
ing, have a
snack, etc.
2. Now is a good
time to look back-
wards over the past
year and see where
we have been.
We are finally out
from under a tough
winter. Brrrr!
3. Getting to
the offices
of the NCC
Focus has
never been
easy.
But this winter
was harder than
usual, especially
that last little bit.
4. Like every other
group the NCC Fo-
cus has been hit by
budget cuts. Our Fo-
cus staff here has
been really great
about accepting my
selling of the Focus
commuter bikes on
Ebay.
We have also
had to out-source
some of the nicer
Focus office
amenities.
5. Because
of the bad
economy we
have been
able to hire
some over-
qualified of-
fice staff,
like this
speed typist
here.
Some of our staff has saved money on clothes for work
by covering up with their pets.
6. In club news, we now have an Enforcer to make sure that
events start on time, after Joel has called the meeting to order
7. The new “WTF?”
photo category has
proved to be very
popular. It also in-
cludes photos
where there might
have been some
digital manipula-
tion.
8. The NCC Board rejected having a special humor
category of images. Too bad about that.
9. Because of that these images of a jet-crane and a re-
luctant bath-taking cat will never be seen. Oh well.
10. Let’s hope
we can all
keep our
heads above
water in the
coming year,
not worry too
much about
the future,
and take
some great
photos!
