Software Limits
By design, there are no limits in
FRED! The user can define as many lenses, mirrors, prisms, custom elements composed of surfaces and curves, assemblies, subassemblies, materials, coatings, scatter models, wavelengths, sources, rays, etc. as the user’s computer resources will allow. Likewise, surface definitions can have as many aspheric and/or polynomial terms as needed.
We built this into
FRED's
architecture because “real world” problems are not constrained; we believe that
FRED
should not be constrained either. As consultants, we’ve worked on system models with over
30,000 surfaces. One of our clients has built a
FRED
model with 800 wavelengths to model a specific dispersive effect. Another client modeled a Fresnel lens with several thousand points defining the cross sectional curve. What will your problem require?
We are passionate about another point related to limits: there are only two
editions of
FRED
and both
have the same optical and analysis capabilities. The only difference between the
two editions is that our Standard edition will raytrace on up to 4 cores and our
Optimum
edition will raytrace on up to 16 cores. We do not market “scaled down” or reduced capability versions of
FRED
and then expect our users to upgrade (for an additional price) when they outgrow its capabilities. Every copy of
FRED
grows to meet the demands of its user.
