abstract

The analysis models of Zernike aberrations of precision conformal aspheric optical windows are built, and the influences on Zernike aberrations of different aspheric optical window shapes and the variation laws of Zernike aberrations of precision conformal optical windows at different gimbal angles are analyzed using the multi-configuration capability techniques of Zemax software. The results of analysis show that the astigmatism of conformal aspherical optical windows is the largest, coma is followed, and spherical aberration is smaller in the range of 45° gimbal angles, and the Zernike aberration coefficients of paraboloid and hyperboloid conformal optical windows are higher than that of ellipsoid conformal optical windows. Therefore the ellipsoid surface function is more suitable for the design of precision conformal aspheric optical windows from the point of view of optical system designs and aberration correction techniques.
