碩士 === 國立中興大學 === 精密工程學系所 === 107 === This thesis proposes the use of the paraxial theory and ZEMAX software optimization to discuss the parameters of the uniaxial collimator and experiment, and to analyze the influence of the parameters of the collimator on the maintenance and collimation of the beam quality. The design direction of the good collimating lens is used to meet the optimal collimating lens design that can be used under various conditions. This paper successfully discusses the collimating performance effects of various collimating lens parameters and uses the light source. Under the initial condition that the beam parameter product (BPP) is 9.075, the optimal collimating lens that can maintain the product in the 1.5% change rate in each condition range of the high refractive material is designed, and the beam parameter product is also achieved with the low refractive material. The rate of change of 1% in a specific range is achieved to obtain the maximum result of maintaining beam quality.
