  • How to define a 3D lenslet

One of the common applications of Luminous in 2D has been the simulation of a lens on top of a device. To facilitate a similiar function in 3D requires creating this 3D lens which can be difficult without using a 3D process simulator. To enable this, additional commands have been implemented into Luminous 3D.

The lenslet is represented by a spherical section on top of the x-z plane. The BEAM statement parameters lens.x lens.y and lens.z are used to define the centre of a sphere. The radius of the sphere is specified with the parameter lens.radius and the location of the planar part surrounding the lenslet relative to the y=0 plane is specified by the lens.plane parameter. Finally the index of refraction of the volume between the lens plane and the device surface is specified with the lens.index parameter.

The volume associated with the lenslet is neither meshed nor simulated and is only used in the ray tracing.
