There are always errors during the fabrication of hyperboloid cylinder-plane lens(HCPL). So the structure of lens does not accord with elements in theory and the collimation preference of lens is not the best. Using ray-tracing method, performance of lens used to collimate laser diode beams was investigated. The influence of lens parameter variation, structural parameters (e), reflective index and distance between light source and lens(l) on the performance of the HCPL was analytically discussed. Results show that the collimation preference of lens can get best with the suitable choice of parameters e,l. This method can be used to design a collimating system of micro-hyperboloid cylinder-plane lens with better performance of collimation and higher beam quality consequently.
