I want to model a micro-lens array in NSC mode (clear aperture < pitch). I tried to use normal lens and array, but this create an array of lens with cylindrical sides (the space between two adjacent lenses is air) which will introduce TIR when AOI of rays exceed critical angle. In real case, the micro-lens array has one side flat and the other side an array of aspherical lenses with circular clear aperture, the substrate of the micro-lens array is a continuous slab so TIR won't happen between neighboring lenses (the space between two adjacent lenses is the lens substrate). How could I model the real case more accurately so TIR won't happen when light enter from one lens to the neighboring lens? I initially tried to use the lenslet array 1, but it has rectangular-shaped lens which is also not the same as what I want to model.
