Biaxial Materials for Birefringent Feature
LightTools’ birefringent capability, which supported uniaxial materials in version 9.0, now also supports biaxial materials. The birefringent capability enables you to trace rays through anisotropic materials (also commonly referred to as birefringent materials) – materials for which the index of refraction is dependent on both the propagation direction of the light and the ray’s polarization state. The biaxial capability allows you to model optical systems using anisotropic materials such as mica and topaz, where the effects of polarization and dispersion are important.
Distributed Simulation Solution
The LightTools Distributed Simulation Module provides the capability to increase the simulation speed of large, computation intensive ray trace processes over a collection of computers. Initially introduced in LightTools 9.0 for forward simulations, this new module now also supports backward simulations.
- Configuration Improvements. To automate tasks when you’re working with LightTools configurations, you can now specify one or more commands to execute when you change from one configuration to another.
- New parametric control: grid expression. A grid expression combines the storage capability of a grid parameter with the power of parametric expression. It allows you to store numeric data generated by a user-entered expression, copy it to use in other LightTools tables, and add it to optimization constraints, optimization merit functions, and tolerancing performance measures. Grid expressions are stored in the LightTools system (.lts) file.
