This paper illustrates a preliminary research about the optical non-contact fingerprint sample method. There are some defects in contact fingerprint sample method. This paper attempts to change cemented doublet combination into super-doublet combination of hemispherical immersion lens. Through using the combination of super-hemispherical immersion lens, CCD camera, and the optical non-contact method to achieve a complete, clear fingerprint image.
