Oslo 6.4 for Lens Design
May 2006Lambda Research Corp.Request Info
LITTLETON, Mass., May 25, 2006 -- Lambda Research Corp., developer of optical software including TracePro
and TracePro Bridge for SolidWorks, announces the latest release
of its lens design software, Oslo. The 6.4 release of Oslo
has more than 40 additions and improvements over the 6.3.4
version, according to the company.
Among the highlights of the
new Oslo 6.4 is the added capability to place multiple interferogram
(INT) files on any optical model surface. Interferogram files can
represent a different source and type of error, e.g. freeform wavefront
or surface deviations. Placing multiple interferogram files on a
surface allows Oslo 6.4 to perform fairly complex tolerance modeling to
predict the as-built performance of real optical systems.
diagram represents typical errors that might be modeled with separate
interferogram files: (A) "print-through" errors of a lightweighted
mirror, (B) atmospheric turbulence, and (C) the composite error that
would be found in the as-built system when interferograms A and B are
Oslo’s implementation of separate interferogram
files allows users to adjust the size and shape of individual errors in
an easy and efficient way. Another highlight of Oslo 6.4, Lambda
Research said, is the addition of a new anamorphic asphere surface type
that extends the standard optical surface sag equation differently in
both the X and Y directions. This addition will allow users to optimize
general anamorphic surface shapes without the control problems usually
associated with spline surfaces. Oslo 6.4 has also added an automatic
check to ensure that users choose catalog glasses within appropriate
wavelength ranges for their models. For example, users will now find it
impossible to incorrectly use visible materials for infrared wavelength
ranges, the company said.
With the 6.4 release, the Hikari, Hoya, Ohara, Schott,
Sumita and Chengdu glass catalogs have been updated with new data,
Lambda Research said. Hundreds of lenses have also been added to the
vendor lens catalogs within Oslo, and data from many vendors such as
Newport, Linos, CVI and Ealing have been updated. More robust ray
tracing algorithms have been implemented for the case of severe offaxis
rays entering a toric surface, and the size of the text window and
spreadsheet buffers have been increased from 2000 to 4000 lines. Also,
improvements have been made to the Linux version to bring it closer to
the same standard as the Windows version.
