Abstract :
To manufacture a gradient index lens (GRIN lens), the radial distribution of refractive index must be formed in the direction of the radius inside the lens. However, with some manufacturing methods, the distribution is not perfectly radial but slightly distorted. In order to evaluate the performance of GRIN lenses, we used the ray tracing method to measure the modular transfer function (MTF).
