In this paper we present and demonstrate, through laboratory measurements and computer ray tracing simulations, a low-cost Lateral Shearing Interferometer (LSI) use to measure the collimation and wave front quality of infrared lasers. The LSI is constructed using a single commercial off-the-shelf uncoated ZnSe window in conjunction with an infrared camera.
