Optical pickup for optical disk and light source for optical pickup

An optical pickup to at least one of reproduce and record data on and from an optical disk, comprising:

• a light-emitting diode (LED) to generate and emit a light;
• a light shaping unit to selectively transmit and collimate a predetermined wavelength of the emitted light, said light shaping unit including a spatial filter having a plurality of pin-holes to correct an aberration of light;
• and
• a focusing lens to focus the collimated light on the optical disk.

An optical pickup to at least one of reproduce and record data on and from an optical disk, comprising:

• a light-emitting diode (LED) to generate and emit a light;
• a condensing lens to condense the light emitted from said LED, to generate a condensed light;
• an optical filter to selectively transmit the predetermined wavelength of the condensed light, to generate a first filtered light;
• a second filter having a plurality of pin holes to limit a transmission range of said first filtered light, to generate a second filtered light as divergent light, said plurality of pin-holes correcting an aberration of the divergent light;
• a collimating lens to collimate the second filtered light, to generate the focused light;
• and
• a focusing lens to focus the collimated light on the optical disk.

A light source module for an optical pickup comprising:

• a light-emitting diode (LED) which emits light;
• a condensing unit which condenses the emitted light;
• an optical filter which selectively transmits a predetermined wavelength of the emitted light;
• a spatial filter, having a plurality of pin-holes, which limits a transmission range of the light selectively transmitted by the optical filter and which transmits a divergent light;
• a collimating lens which condenses the divergent light transmitted by the spatial filter;
• and
• a housing which retains the light emitting diode, the condensing unit, the optical filter, the spatial filter and the collimating lens in a fixed relationship.
