Binary 2 (non-sequential geometry objects)

The Binary 2 object is a standard lens with a diffractive optic phase profile similar to the Binary 2 surface type on the front face. The Binary 2 phase profile adds phase to the ray according to the following polynomial expansion:

where N is the number of polynomial coefficients in the series, A_i is the coefficient on the 2i^th power of ρ, which is the normalized radial aperture coordinate. The coefficients A_i all have units of radians ( 2π radians is one wave).

The definitions for the parameters are:


Parameter #	Description	Face Name	Face #
1	The radius of curvature of the front face. Use zero for infinity (flat).	Front	1
2	The conic constant of the front face.	Front	1
3	The clear semi-diameter or semi-diameter to the clear aperture of the front face. Use a negative value to yield the hyperhemispheric sag point.	Front	1
4	The radial aperture to the edge of the front side of the lens.	Front	1
5	The center-to-center thickness of the lens.	Side	0
6	The radius of curvature of the rear face. Use zero for infinity (flat).	Back	2
7	The conic constant of the rear face.	Back	2
8	The clear semi-diameter or semi-diameter to the clear aperture of the rear face. Use a negative value to yield the hyperhemispheric sag point.	Back	2
9	The radial aperture to the edge of the rear side of the lens.	Back	2
10	The diffraction order M.	Front	1
11	The normalization radius. The x and y coordinates are normalized to this value. This keeps all coefficients in units of radians.	Front	1
12	The maximum term number.	Front	1
13-242	The values of the coefficients on the polynomial terms.	Front	1

This object does not diffract rays correctly if the front surface is made hyperhemispheric. See also the Binary 1 object.

Face Numbers: Front face is Face 1, back face is Face 2, and all other faces are Face 0.
