MOUNTAIN VIEW, Calif., March 12, 2019 /PRNewswire/
-- Synopsys, Inc. (Nasdaq: SNPS) today announced the release of version 8.7 of its LightTools® illumination design software for the modeling, analysis, and optimization of
illumination optics. LightTools 8.7 introduces advanced capabilities to help optical designers pinpoint and correct stray light
issues—including ghost images and flare—early in the design process. Designers can quickly prototype their opto-mechanical
systems, explore the interactions of light with system components, and identify sources of unwanted surface interactions that
impact system performance. LightTools stray light analysis is particularly useful for improving the design of next-generation
illumination optics used in space-borne telescopes, infrared optical systems, consumer electronics, autonomous vehicles, and
AR/VR/MR applications.
The comprehensive toolkit of stray light analysis features in LightTools 8.7 is supported by fast performance,
industry-leading accuracy, and efficient workflows. Highlights include:
- Support for the Harvey-Shack and ABg scattering models, as well as a scatter evaluation tool, to simulate highly-polished
surfaces. In addition, a new microfacet optical property allows rough surfaces to be precisely modeled using a single, on-axis
bidirectional scattering distribution function (BSDF) measurement, greatly reducing measurement costs and time, or by direct
measurement of the surface's slope distribution.
- New receiver filters that track ray-surface interactions and identify contributions from ghosts and flare. These filters
can help designers isolate imaging rays or specular and scatter illuminance.
- The Ray Path analysis enhancements that deliver increased performance and provide detailed data to locate ghost images.
This data can identify how much unwanted power is incident on a detector, for example, or identify the peak power when looking
for distinct ghost images and evaluating a system prone to laser damage.
- Options for specifying a Normalized Power Range to filter analysis results to a subset of ray paths based on the total
power collected in each path.
- Scatter aiming enhancements that provide additional flexibility when specifying aim areas, with options for polygonal and
surface-based shapes, as well as the ability to position the aim area in global coordinates.
- Contamination scattering for modeling the effects of dust and other particulates that may contaminate optical surfaces,
such as mirrors.
"The latest LightTools release represents a major advance in stray light analysis, with versatile features such as new
scattering models to accurately simulate opto-mechanical surface characteristics and filters to identify sources of unanticipated
stray light effects," said George Bayz, vice president of Synopsys' Optical Solutions Group.
"Companies using LightTools can achieve significant product development cost savings by identifying and fixing stray light issues
early in product development."
Additional enhancements in LightTools version 8.7 include:
- A source power scaling feature allows users to adjust the power of model sources and see the results immediately. The
feature dramatically speeds optimization and analysis of illumination system color rendering.
- LightTools' unique modeling capabilities for freeform optics in illumination systems have been enhanced with design
features to correct distortion caused by secondary optics, such as cover plates, turn mirrors, and projection assemblies.
- Expanded design features for biomedical optics, horticultural lighting, light guides, and street lighting.
- Significant additions to LightTools material and optical property libraries, which can simplify and speed model setup and
analysis, as well as additions to the example model library, which provides models that demonstrate how to use LightTools
features.
