| 摘要 |
An optical element and a manufacturing method thereof are described. An optical material is pressed in a holder through a mold, so as to form an optical element with an optical lens embedded in the holder. A groove in the holder has a guiding face, and the guiding face is obliquely disposed in a direction towards a mirror with a relatively smaller radius of curvature of the optical lens, so as to guide the optical material to truly enter the groove, thereby enhancing gas tightness and precision between the optical lens and the holder.
