This is a step-by-step demo of reshaping lens design for a laser beam with Gaussian profile. This lens is to transform the Gaussian profile to homogeneous illumination in the imaging plane. Optical model, math equation, ray tracing operands and optimization process are introduced.

Input laser beam profile:

Optical structure:

Math calculation of coordinates in Excel:

Output illumination profile:
