Binary 1 (non-sequential geometry objects)

The Binary 1 object is a standard lens with a diffractive optic phase profile similar to the Binary 1 surface type on the front face. The Binary 1 phase profile adds phase to the ray according to the following polynomial expansion:
where N is the number of polynomial coefficients in the series, M is the diffraction order, and Ai is the coefficient on the ith extended polynomial term. The polynomials are a power series in the normalized coordinates x and y, as described in "Extended Odd Asphere Lens". The coefficients Ai 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 2 object.

Face Numbers: Front face is Face 1, back face is Face 2, side face is Face 0.
