The roles of aspheric is to Simplify the system structure, shorten the tube length, reduce the weight of the system, improve the imaging quality, and make the optical system extend to the infrared and ultraviolet bands.With the development, the cost of aspheric surface processing has been constantly reduced and its application has been increasing, especially in aerospace, science and technology, digital imaging and many other fields.Aspherical lenses are used to replace spherical lenses,The most significant advantage is that the spherical aberration caused by spherical lenses in collimating and focusing systems can be corrected.Sunday Optics manufactures high precison aspheric lens, the accuracy can be 0.5-10um. We professionally make complicated optical system,from design, manufacture to assambly. Material range from optical glass to infrared glass with Traditioanl polish and CNC polish.
