Classes

ParaxialRays(y, u, z, wavelength)

Class representing paraxial rays in an optical system.
class ParaxialRays(y: ArrayLike, u: ArrayLike, z: ArrayLike, wavelength: ArrayLike)[source]#

Class representing paraxial rays in an optical system.

Variables:

  • y – The y-coordinate of the rays.

  • u – The slope of the rays.

  • z – The z-coordinate of the rays.

  • wavelength – The wavelength of the rays.

Methods:

propagate (t) – Propagates the rays by a given distance.

propagate(t: ScalarOrArray)[source]#

Propagates the rays by a given distance.

Parameters:

t – The distance to propagate the rays.

record_on_surface(surface: Surface) → None[source]#

Dispatch to the surface’s paraxial record method.

Parameters:

surface (Surface) – The surface to record onto.

rotate_x(rx: ScalarOrArray)[source]#

Rotate the rays about the x-axis.

rotate_y(ry: ScalarOrArray)[source]#

Rotate the rays about the y-axis.

rotate_z(rz: ScalarOrArray)[source]#

Rotate the rays about the z-axis.

trace_on_surface(surface: Surface) → ParaxialRays[source]#

Dispatch to the surface’s paraxial trace kernel.

Parameters:

surface (Surface) – The surface to trace through.

Returns:

The traced paraxial rays.

Return type:

ParaxialRays

translate(dx: ArrayLike, dy: ArrayLike, dz: ArrayLike)#

Shifts the rays in the x, y, and z directions.

Parameters:

  • dx – The amount to shift the rays in the x direction.

  • dy – The amount to shift the rays in the y direction.

  • dz – The amount to shift the rays in the z direction.
