rayoptics.raytr package

Package for optical ray tracing and calculations

The raytr subpackage provides core classes and functions for optical ray tracing and analyses. These include:

  • Base level ray tracing, raytrace

  • Calculation of wavefront aberration, waveabr

  • Specification of aperture, field, wavelength and defocus, opticalspec

  • Higher level ray tracing, in terms of aperture, field and wavelength, trace

  • Functions setting vignetting and clear apertures and support for pupil exploration, vigcalc

  • Tracing of fans, lists and grids of rays, including refocusing of OPD values, analyses

  • Exception classes for reporting ray trace errors, traceerror

  • Sample generation for ray grids, sampler

The overall optical model is managed by the OpticalModel class

class RayResult(pkg, err)

Bases: tuple

A RayPkg and either a RayError or None

err

a RayError or None, if success

pkg

a RayPkg

class RayPkg(ray, op, wvl)

Bases: tuple

Ray and optical path length, plus wavelength

op

optical path length between pupils

ray

list of RaySegs

wvl

wavelength (in nm) that the ray was traced in

class RaySeg(p, d, dst, nrml)

Bases: tuple

ray intersection and transfer data

d

ray direction cosine following the interface

dst

geometric distance to next point of incidence

nrml

surface normal vector at the point of incidence

p

the point of incidence
