What’s
New in This
Update?
The update to version 13.41 incorporates the
following changes:
Features:
1. The dialog MPE now has three new
checkboxes where you can request some commonly used ray sets for your
lens drawings. This will save some time in the event those rays
are satisfactory.
2. A new dialog, MSB, lets you run a simple BTOL evaluation just
by selecting a few items and filling in some boxes. For many new
users, this should be a great time saver.
3. The RSOLID display control bar now has two print buttons
instead of one. One prints the solid drawing on a vertical page,
while the other rotates the picture so it fits the long way, which
looks better. You could control this with switch 81 before, but
it was a pain if you forgot to set it first. Now the two buttons
do it for you.
4. The text annotation editor now has an option to rotate the
text by 90 degrees on the drawing. This is sometimes handy
– especially if you have pasted an RSOLID picture into a graphics
window with switch 81 on, which rotates the picture to better fill the
drawing area, and you want the text lined up the same way. It
will show up at 90 degrees on the monitor and printout, but of
course you will then rotate the page as it should be when you print it
out.
Bugs Fixed:
1. The solid drawing features did not honor a
UAP type 3 edge declaration in all cases.

Version
13.40
The update to version 13.40 incorporates the
following changes:
Features:
1. PAD now has a new ray selection, which can
be applied to the drawing or perspective drawing option, and which
traces only a single ray – which you can select with two slider
bars that pop up when you use this new feature. If you ever
wanted to trace that ray in PAD, now you can. Give this a try;
you’ll like it.
Bugs Fixed:
There were no bugs reported this update.

Version
13.39
The update to version 13.39 incorporates the
following changes:
Features:
1. Testplates of Ross Optical are now bundled
with SYNOPSYS.
Bugs Fixed:
1. Chapter 8 of the Tutorial Manual gave an
incorrect example of the use of the TH adjustment for BTOL.
There, it said
To adjust the axial position of element 2 (surfaces 3 and 4) we would
enter ADJ 3 TH 2.
This should have read ADJ 2 TH 2. The explanation in 12.1.2 of
the UM was correct.
2. BTOL would crash if any of the image points to be toleranced
were completely vignetted.

Version
13.38
The update to version 13.38 incorporates the
following changes:
Features:
1. The FOCUS command has been enhanced.
It now works with color selection “M”, and it now executes
a quick SYNOPSYS run to find the defocus. Before, it worked on
only one color at a time and had its own search algorithm – which
was not always successful with AFOCAL lenses. This is better.
2. We have posted a link on our website to a movie of a
colloquium talk that Mr. Dilworth gave in the fall of 2008 at the
Optical Sciences Center at the University of Arizona. This is
titled “Lens Design 40 Years On:
Where We Were, Where We Are, How We Got There.” All
users are encouraged to have a look at this movie; it describes
numerous features and methods that you may not know about.
Bugs Fixed:
1. If you did a CHG that replaced a glass type
that was assigned dn/dt coefficients with one that was not, the old
coefficients remained in effect.
2. Varying both the RD and CC of a Fresnel surface did not work
as it should.

Version
13.37
The update to version 13.37 incorporates the
following changes:
Features:
1. The DXF files produced by the HARD DXF
command and by the RPER dialog have been improved. Some
third-party programs could not read the files before, while others
worked fine. We hope that this improvement will fix the
problem.
2. A new command DSOLID has the same input as RSOLID, but creates
a solid-model DXF file instead of an onscreen picture. Users are
encouraged to test these DXF features with their favorite CAD program
and let us know if they encounter unexpected results.
3. The OSD website www.osdoptics.com now has a link to Google
Translate. There you can see the page translated into any of
several languages. We hope this will be useful to our customers
who are not native English speakers.
4. The numeric results printed on the UCLOCK plot are now lined
up so they are easier to read.
5. The THERM program now prints and displays a warning box in the
event that one or more materials in your lens lack thermal
coefficients. Before, you could get the warning information with
the THERM TEST command – but not all users remembered to take
this precaution. Now the warning is automatic.
Bugs
Fixed:
1. If you put a UAP aperture on surface 1 of a
system with a Gaussian object type OBG, the UAP was ignored.

Version
13.36
The update to version 13.36 incorporates the
following changes:
Features:
1. The new command SPACERS will produce a table
giving the length of the spacer required between all lens elements
separated by AIR. This calculation adjusts the axial airspace by
the surface sags on both sides so you can quickly design your lens cell
and be sure that the lens separations will be correct. You can
also find this command in the MUT dialog.
Bugs Fixed:
1. There were no bugs reported this update.

Version
13.35
The update to version 13.35 incorporates the
following changes:
Features:
1. Seven radiation-resistant glass types have
been added to the Schott glass table. These are types BK7G18,
LF5G19, LF5G15, K5G20, LAK9G15, F2G12, and SF6G05. If any users
know of other useful glasses that are not now in the tables, please let
us know. Manufacturers do not notify us when new glasses are made
available, in spite of repeated requests, so we often do not know about
them until someone asks.
Bugs Fixed:
1. UCLOCK would display an error message if any
of the required weights were zero. Now it substitutes a very
small weight so everything works.

Version
13.34
The update to version 13.34 incorporates the
following changes:
Features:
1. We have updated the Ohara glass catalog with
revised interpolation coefficients for glass type S-BSM18, which was
listed with incorrect data in their published document.
2. The ZFILE zoom lens feature has been enhanced. The Zoom
Toolbar now has a button that opens a new dialog showing a horizontal
slider. When you move this slider you can watch the elements
zooming on the Pad display, and you can monitor the image quality to
check if there are positions that should have been controlled but were
not. This feature uses the algorithm in CAM to get zoom data at
100 points over the range, which makes the zoom look very smooth.
3. The CAM feature itself has been enhanced. Before, the
zoom data were interpolated up to fourth order. Now the order is
just the number of zooms defined, which gives a more accurate fit to
the original ZFILE data if a larger number of zooms were defined.
Bugs Fixed:
There were no bugs reported this update.

Version
13.33
The update to version 13.33 incorporates the
following changes:
Features:
1. The onscreen glassmap display now shows the
partials of glass model glasses along with those of the glasses in the
table then displayed, if you ask for a graph of those partials.
This lets you see what kind of behavior the GLM variable is modeling
– so you can substitute a real glass with similar properties if
one exists. That way the secondary color should come back close
to what the model predicts.
2. Say you’ve designed a very nice 5-element lens that uses
expensive glass. You also have a 6-element design with cheaper
glass. Which to you build? A new feature, GCOST, will
examine all of the glass types and element shapes in the lens and
prepare a table with the estimated cost of lens blanks. There are
two sections: one assumes you will buy flat blanks, and the other
molded blanks.
This feature reads the relative cost of each glass type from those
tables that contain those data. Currently, the Hoya, Guangming,
and Lzos do not.
Bugs Fixed:
1. BTOL did not print the tolerance for the
conic constant, although it was part of the budget.

Version
13.32
The update to version 13.32 incorporates the following changes:
Features:
1. The glass model (GLM) has been
enhanced. This feature uses a 9-term polynomial that gives the
approximate index of any glass on the glass map, at any wavelength,
given only the values of the wavelength, Nd and Vd. (Modeled that
way, the glass becomes a continuous variable that can be optimized
along with radii and thicknesses.) That polynomial worked quite
well over the CDF spectral range, but failed outside it. The new
polynomial has 11 terms and works over the range 0.8 to 0.35 um.
We have used it to design an apochromat covering that range, and the
program was able to find rather ordinary glasses that gave
diffraction-limited performance.
2. DSEARCH has been improved. If it encounters ray failures
when evaluating a potential design, it takes steps to resolve the
failure and continue optimization. That process is now more
robust, resulting in more cases evaluated and fewer skipped.
3. The MTF over field feature (MOF) can now draw the MTF values
at up to four spatial frequencies, as a function of field point.
Before, it could only draw one. (The dialog entry still supports
only one, so you have to use the command form if you want more.)
Bugs Fixed:
1. The new ASC aberration (slope control)
disabled the AEC (edge control) aberration. Now both work.
2. The mnemonic for the sensitivity reduction aberration (ECO)
conflicted with the fifth-order aberration ECOMA. So it has been
renamed ECM.
3. In some cases, after you ran the ANNEAL program, the progress
bar, which looks like a thermometer, stayed onscreen instead of closing.
