Abstract

An objective lens comprises two plastic elements that will be able to read and write CD, DVD and Blue-ray Disc (BD). Adjusts axial position of the one piece of the two plastic elements, to changed the NA value. Simultaneously compensate spherical aberration and chromatic aberration by application of two plastic elements. All working distance are above 0.67 mm and the wavefront aberrations are below 0.01 lambda.
