Abstract: An optical lens, mold for optical lens and manufacturing method thereof are provided, wherein the optical lens includes a spiral surface spiraling around an axial direction and an intermediate structure around which the spiral surface spirals, the intermediate structure extends axially relative to a side of the spiral surface, and two ends of the spiral surface defines a stepped difference. The structure of the mold and the optical lens are correspondingly complementary. The manufacturing method of the mold includes following steps of: providing a base, the base including a processing surface; processing the processing surface to form the spiral surface, the intermediate structure and the stepped difference of the mold.

Abstract: An optical fiber module contains: a circuit board, a photoelectric assembly, a control assembly, a body, and a light transmission set. The body includes a first accommodation groove, a second accommodation groove accommodating the optoelectronic assembly, a first reflection portion facing the circuit board, a lens set accommodated in the second accommodation groove and aligning with the first reflection portion, a guide orifice, a converging lens extending from the guide orifice, and a second reflection portion adjacent to the converging lens, wherein the second reflection portion has a second reflecting face corresponding to the converging lens. The light transmission set includes multiple passing faces formed on a first surface thereof so as to face and correspond to the first reflection portion of the body, and the light transmission set includes multiple complete reflecting faces formed on a second surface thereof away from the multiple passing faces individually.

Abstract: An optical fiber module includes a main body and at least one optical conducting set. One surface of the main body is formed with a recess set and an accommodation groove, the main body is formed with a reflection slot and a lens slot, disposed with a lens set on a surface of the lens slot, and disposed with a third lens close to the accommodation groove; the optical conducting set is disposed in the accommodation groove and includes a base material and at least one optical conducting member, one surface of the base material is formed with an optical pervious plane close to the third lens which is substantially corresponding to the optical pervious plane, the optical conducting member are formed on two surfaces of the base materials, and can allow a light source with different wavelengths to pass and allow light sources with other wavelengths to be reflected.

Abstract: An optical communication module contains: a lens element, a fixer, and at least one optical fiber. The lens element includes a groove, a body, a top face, a light input face, at least one collimator lens, and a reflective bevel face. The at least one collimator lens is located within an orthographic projection range of a vertical viewing angle of the reflective bevel face, and the body has a light output face. The fixer is mounted beside the body and includes an accommodation recess and at least one focus face, wherein the at least one focus face corresponds to an orthographic projection range of a horizontal viewing angle of the light output face. The at least one optical fiber is inserted into the accommodation recess, and a glue is filled into the accommodation recess so that the at least one optical fiber is adhered in the lens element.

Abstract: A beam splitter contains: a body, a main reflection portion, a sub reflection portion, and a refraction portion. The body includes an inlet and an outlet. The main reflection portion is located on a first side of the body, and the main reflection portion and the outlet have a first rotating angle and a second rotating angle respectively so that the main reflection portion reflects an external beam to produce a main beam. The sub reflection portion is located on the first side of the body, and the sub reflection portion reflects the external beam to produce a sub beam. The refraction portion is located on a second side of the body and has a third rotating angle different from the inlet, the sub beam projects out of the refraction portion to produce a deflective projection angle of the sub beam.
