Optical design of projection systems –Lithography lens and ultra-short throw LCoS projector


Projection systems for lithography lens and LCoS (liquid Crystal on Silicon) projector are designed and fabricated. Based on Koehler illumination and tele-centric lens type of projection systems, optical parameters are provided. The best performance of systems could be achieved.

Ching-Yao Huang Simulation of Power Distributions in Progressive Addition Lenses


This study is to simulate the whole-surface power distributions in progressive addition lenses (PALs) by using a governing conicoid equation to generate the front and back surface shapes. The results show that the spherical equivalent power and astigmatism are strongly affected by the add power, progressive corridor length, and asphericity.

Chao-Hsien Chen General Theorem of the Variation of Aberrations of Optical Lenses


A brief review of our research on modelling and evaluating the variations of the primary optical aberrations (including the Seidel aberration, chromatic aberrations and secondary spectrum) of conceptual thin and thick lenses is given. Further, we have proved that lenses with the same focal length but different thicknesses may provide equivalent aberrations under some conditions.

Cheng-Hao Ko Generalized Aberration Reduction Procedure of a Concave Diffraction Grating for Hyperspectral Imaging


An optimization process to control the aberration of a concave grating is developed. The approach has a dramatic reduction in aberration and great improvement in spectral resolution.

Jyh-Chyang Yen The Study of Alvarez Lens for Reducing Spherical Aberration


An unequal ratio Alvarez lens with minimum lateral shift has been designed, which can minimize the longitudinal spherical aberration. The design consists of two-group lens pairs with unequal ratio structure. The rms spot size radius decreases from 3.15 μm for the single lens-pair to 1.75 μm for two-group lens pairs.
