We present a simple and stable optical performance evaluation and aligning method for a solid immersion lens (SIL) assembly with a wedge plate lateral shearing interferometer (LSI). There are many advantages in the use of the wedge plate LSI compared with a current SIL measurement method using a Twyman-Green interferometer. We designed the thicknesses, wedge angles, materials, and reflectances of the first and second surfaces of the wedge plate to be 1 mm, 0.02°, fused silica and 21, and 30%, respectively. Simulation and experimental results are well matched in quantitative analyses at shear ratios of 10, 40, and 70%. On the basis of simulation results for an aberrated SIL assembly with many misaligned cases, we suggested the use of the aligning process with the wedge plate LSI.
