摘要： An optical image capturing system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element and the third lens element have refractive power. The fourth lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The fifth lens element with positive refractive power has a convex object-side surface, wherein at least one inflection point is on at least one surface thereof. The sixth lens element with negative refractive power has a concave object-side surface. The surfaces of the fifth and the sixth lens elements are aspheric. The optical image capturing system has a total of six lens elements.

摘要： An optical fingerprint identification system includes a base, a photo sensor, a light emitting layer and a cover. The photo sensor is disposed on the base. The light emitting layer is disposed above the photo sensor, and the light emitting layer includes a light emitting element. The cover is disposed above the light emitting layer. The optical fingerprint identification system further includes a light path adjusting element between the photo sensor and the cover. The light emitting element is disposed away from the light path adjusting element and the photo sensor in a sideway direction that is different from a stack direction of the optical fingerprint identification system.

摘要： This disclosure provides an optical image capturing lens system comprising: a positive first lens element having a convex object-side surface, a negative second lens element, a positive third lens element having a convex image-side surface, a fourth lens element having a concave object-side surface and a convex image-side surface; and a positive fifth lens element having a convex object-side surface at a paraxial region thereof, both of the object-side and image-side surfaces being aspheric, and at least one inflection point is positioned on at least one of the object-side and image-side surfaces thereof. When particular relations are satisfied, the angle at which light projects onto the image plane can be efficiently controlled for increasing the relative illumination and preventing the occurrence of vignetting.
