Lenslet Array 2
The array aspects of this object are provided for back compatibility with older versions of OpticStudio. A more efficient method that ray-traces more quickly is to make a single lenslet and then create an array using the Array Object - see " Array " for details.
A Lenslet Array 2 object consists of an array of rectangular volumes, each with curved front and back faces. The faces may be plane, sphere, or conic asphere.
The Lenslet Array 2 is defined by these parameters:
| Parameter # | Description | Face Name | Face # |
| 1 | The X Half-Width in lens units of each lenslet. | NA | NA |
| 2 | The Y Half-Width in lens units of each lenslet. | NA | NA |
| 3 | The thickness along the local Z axis of each lenslet. | Side | 0 |
| 4-5 | Unused. | NA | NA |
| 6 | The radius of curvature of the front face of each lenslet, use zero for a plane. | Front | 1 |
| 7 | The conic constant of the front face of each lenslet. | Front | 1 |
| 8 | The radius of curvature of the back face of each lenslet, use zero for a plane. | Back | 2 |
| 9 | The conic constant of the back face of each lenslet. | Back | 2 |
| 10-11 | The number of lenslet elements in x and y. If the total number of lenslets is large, it is generally much faster to use a single lenslet (set parameters 10 and 11 both equal to 1) and then use the Array object to create the array of lenslets. The Array object method is much more powerful, uses less memory, and will generally load and trace much faster than using a large number of lenslet elements. See "Array" . | NA | NA |
The reference coordinate is the center of the front face. Face Numbers: Front face Face 1, back face Face 2, all other faces Face 0.
