Hexagonal Lenslet Array
The hexagonal lenslet array object models a rectangular volume with a front face consisting of a hexagonal array of even aspheric lenslets. To make the part rectangular, partial hexagonal lenses are added along the sides as required. The even asphere surface sag expression is identical to that of the Even Asphere Lens object (see " Even Asphere Lens " ). The back face is plano. The object uses the following parameters:
| Parameter # | Description | Face Name | Face # |
| 1 | The number of columns (must be an odd positive integer). | Front | 1 |
| 2 | The number of rows (must be an odd positive integer). | Front | 1 |
| 3 | Draw as flat: If this is set to 1, the front face of the lenslet array is drawn as flat. OpticStudio uses this flat face as a first guess for raytracing and then iterates to the actual curved array surface. This can speed up rendering times, but shouldn't be used if rays have large angles of incidence on the front face of the object. | NA | NA |
| 4 | Width: This is the full width of a single hexagon lenslet in lens units. | Front | 1 |
| 5 | Thickness: The thickness of the lenslet, measured along the +z axis from the center lenslet vertex to the back plano face. | Side | 0 |
| 6 | Radius: The radius of curvature of each lenslet in lens units | Front | 1 |
| 7 | Conic: The conic constant of each lenslet. | Front | 1 |
| 8-15 | The aspheric coefficients on the powers of r. | Front | 1 |
The reference coordinate is the center of the front face. Face Numbers: Side faces Face 0, front face Face 1, back face Face 2.
