Purpose: We have attempted to remove one lens from contact analyzer in the optical existing system to simplify the system. This optical system design has been optimized for high performance by reducing the aberration of the system. We are then able to obtain a clear image of the contact lens surface.
Methods: The wavelength was used the Fraunhofer C, d, F line (, , and respectively). For the optical performance analysis of an existing contact lens analyzer and optimal design of the optical system, the reference wavelength was set to d-line. The object height of the full field was set to 5 mm. The program Zemax 14.2 was used to the optical analysis of the reference model analyzer, and the optimized optical system design of the new analyzer.
Result: The Spot diagram RMS radius of the new contact lens analyzer has improved the performance by 42.51% compared to the previously existing analyzer. In the image quality which affects the spherical aberration by 96.96%, in astigmatism by 68.39%, in the longitudinal chromatic aberration by 39.29%, and in the lateral chromatic aberration by 95.97% respectively. The aberration performance of the field curvature and distortion has respectively improved, 82.09% and 66.05%.
Conclusion: We have designed a new optical system which reduces aberrations and uses a fewer number of lenses than the old contact lens analyzer. The optimized contact lens analyzer is available at low-cost. Thus the optimization of high-performance is achieved.
