What’s New in This Update?Version 15.49The update to version 15.49 incorporates the following changes:Features:1. It is now possible for your annotated text to be displayed in Courier font in the graphics windows. This is intended for when you want to copy some printed text, such as Zernike terms, to paste on the drawing. The default text does not line up columns the same way, since it is proportional spaced..2. DSEARCH now accepts an optional DAMP input and will add it to the optimization MACro. Sometimes a high damping makes it work better.3. A new variable is available. The mnemonic PGM declares a surface PLASTIC and varies the index and Abbe number so that they both move along a curved line that passes through the area where plastics are to be found. If a surface is already declared PLASTIC, the usual GLM variable does the same thing. This should avoid problems with the very small area previously modeled with boundary conditions.4. If your lens has aspherics defined as spherical or conic with G-term coefficients, a new variable DCA will vary the coefficients, so you don't have to list them individually, as before. You can select to vary only the axially-symmetric or rotationally-symmetric terms if you wish.5. DSEARCH ... SINGLE now accepts the case you want to process as a decimal number. It still accepts a series of 1's and 0's, or P's and N's, as before.6. PAD now lets you define a command link string for each of the five views in each of the six configurations. Before, a single string applied to all.7. The Shape Option dialog for converting to or editing a Zernike surface now has a check box where you can select to make the surface go through the vertex. (Zernikes can have a nonzero sag at the origin, if this is not selected.)8. We have modified one of the common blocks of the source code, and users who have implemented the USERDLL.sln to customize the program for their needs will need a new fortranstructures.h file. Please contact OSD and request this file before you use this new update.Bugs Fixed:1. ELD element drawings did not display mirrors whose thickness was declared CMIRROR correctly.2. If switch 1 is off, the optimization could fail.3. The SPS spreadsheet display did not show up properly on small notebook computers. Now it shows the lens data in groups of 25 instead of 50, so it works on small screens too.4. If you ran AAA (Automatic Aspheric Assignment) and killed the process before it was finished, it loaded the current contents of the requested library location, which would have been overridden had the job finished.5. The new protocol for selecting text in the Command Window would turn off the selection as soon as you pressed any key. But that disabled the <ctrl>C copy and <shift>extend-selection functions. Now those are allowed.SYNOPSYS™ Version 15.49 12/12/18. Download. (16.9 MB)

What’s New in This Update?Version 15.41The update to version 15.41 incorporates the following changes:Features:1. A new shape is available: type USS 26 models a 3-layer DOE. This is similar to the 2-layer version USS 20, but has a layer of plastic between the two kinoforms and yields higher diffraction efficiency.2. A new RLE entry LOG log will set the log number assigned to the lens to the entered value. Similarly, the command LOG LENS log will assign the number, as will the AI sentence LENS LOG = log.Bugs Fixed:1. Object type OBD did not support LRAYS.2. ZDWG did not always position the lens drawings correctly.3. The PAD SCAN button did not work properly with ZFILE zoom lenses assigned object type OBD.4. Diffraction analysis did not work properly for DOEs in polarization mode.

What’s New in This Update?Version 15.38The update to version 15.38 incorporates the following changes:Features:1. AED now has a new option that will do an additional optimization run, after you agree to delete the selected element, where the targets on that element are controlled via "C" aberrations rather than by "M". This should reduce the thickness and power to very close to zero, so when that element is removed the ray paths are unchanged. Also, the former PIA parameter has been renamed PEL. The power is now controlled by taking the difference between the curvatures on both sides. Before, it used the first-order power, which was not appropriate if the element was cemented.2. The number of allowed variables is increased from 200 to 400.3. A new surface shape, USS 24, models a NURBS surface, as does type USS 15 -- but in this case the data area can contain up to 400 points instead of the 81 of the other shape. This form has a new restriction: only five slots are available, and you must select one of them when you assign this shape.4. If switch 95 is turned on, KICK and ANNEAL will not alter GLM variables. (It still does not change the conic constant or general aspheric terms.) This should avoid ray failures that might occur in some systems.5. PAD now shows an element with an aspheric on side 1 with a green surface number circle, and with blue if the aspheric is on side 2. If both sides are aspheric, the color is black or white.6. A Zernike surface can now be assigned a new ZVZ setting. This will make term G 37 (a constant term) automatically adjust itself so the vertex of the surface actually goes through the axis point given by the preceding thickness. Since some Zernike terms are nonzero even at the axis, it is possible for the surface to wind up a distance from this vertex point otherwise -- which is an unwelcome surprise. Bugs Fixed:1. A DO MACRO loop that ended up in one of the image analysis features did not loop.2. DWG did not correctly render a flat surface assigned a decentered aperture.3. DSEARCH did not utilize an existing system (with USE CURRENT) if that system had aspheric surfaces.4. SOUT operating on a surface within a tilt or decenter group did not work correctly.5. The polarization phase difference was not properly calculated by IFP6. ADEF ... FRINGES produced a blank picture.7. The WorkSheet SEL slider sometimes produced a corrupted edit pane.

What’s New in This Update?Version 15.37The update to version 15.37 incorporates the following changes:Features:1. The EDGE calculation now takes the actual CAO of both sides of the element. Before, it used the smaller of the two.2. A new command, PSURF, plots the state of polarization at each surface.3. The glass-map display now has radio buttons to instantly show a selected glass table.4. PAD now shows the date and time when it is redrawn. This will help in documenting your work if you make hardcopy printouts.5. DSEARCH now quits nicely if it cannot find any valid solutions.Bugs Fixed:1. The FRINGES / PUPIL sequence did not work properly if the lens was in polarization mode.2. The custom glass table did not work if you added a GFIT or GDF glass type.

What’s New in This Update?Version 15.36The update to version 15.36 incorporates the following changes:Features:1. DSEARCH and ZSEARCH now both have an AFOCAL option. To use it, you specify the desired output beam semi aperture (paraxial YA) with the "FNUM" parameter in DSEARCH, and the "GIHT" parameter in ZSEARCH. Those parameters lose their usual meaning with an AFOCAL system, so we have re-purposed them for this new feature.Bugs Fixed:1. The PCV option, when applied to a Zernike surface, only picked up terms 1 through 39. Now it gets all 51 terms.2. Assigning a CAO to surface type USS 16 did not work correctly.3. If you assigned a tilt or decenter to the center surface of a waveplate (which makes no sense) the program would hang. Now it won't let you.

What’s New in This Update?Version 15.35The update to version 15.35 incorporates the following changes:Features:1. A new surface shape is available. USS 23 models a Fresnel lens with explicit zones, but unlike USS 3 and 4, the substrate can be curved.2. The interferometer routines have been enhanced. IFR, which creates a reference wavefront, now has an option to set the center point at the axis instead of at the chief-ray point, and IFP, which calculates the difference between that reference and a different wavefront, can now use the same center point. This lets you model an interferometer where the two wavefronts have different incident angles, which would not have shown up before. You can also now input a phase shift between the wavefronts, and if the lens is in polarization mode, these routines will calculate the phase difference between the two wavefronts and offset the fringe pattern accordingly.3. The PUPIL routine can now plot wavefront fringes at the exit pupil. Before, the OPDs were calculated there but the plot coordinates were taken at the normalized entrance pupil. If you analyze a laser beam shaper, for example, the ray distribution at the exit pupil will be different, and the new option will remap the rays accordingly. 4. Both IFP and PUPIL can also now do some post processing of the fringe pattern, printing either an X or Y trace through the center of the pattern -- or a Fourier transform of that trace.Bugs Fixed:1. The CAM calculation sometimes reported overlapping lens groups when they in fact did not overlap.2. The AMS monitor did not work for flat wiindows.3. DSEARCH did not work with Gaussian object type OBG.

What’s New in This Update?Version 15.34The update to version 15.34 incorporates the following changes:Features:1. A new command, LLT size, lets you change the size of the edit handles on the lens layout tool.2. New variables CAX and CAY will vary the center point of a hard CAO aperture. These mnemonics are also valid AANT entries.Bugs Fixed:1. The ACOLOR option, valid for RSOLID, crashed RPER.2. The CAM ... SET sequence did not work if the object type was OBD.3. The SPEC listing indicated that the object index was the target of a pickup, when it was not.
