摘要： PROBLEM TO BE SOLVED: To provide an imaging lens for a solid-state imaging device whose optical performance is excellent, whose performance degradation is restrained to be little with respect to temperature change and which is inexpensive and compact by appropriately arranging a glass lens and a plastic lens.
SOLUTION: The imaging lens forming an image on the solid-state imaging device is constituted of three lenses. It is constituted of a first positive lens (L1), an aperture diaphragm (ST), a second positive lens (L2), and a third negative lens (L3) whose concave surface faces an image surface side in order from an object side. Either the first or the second lens (L1 or L2) is the glass lens and the other is the plastic lens, and the third lens (L3) is the plastic lens. The lens constitution satisfies a conditional expression: 0.3

摘要： PROBLEM TO BE SOLVED: To provide an image pickup lens which is constituted so that desired optical performance can be maintained, a back focus distance can be sufficiently secured, a high telecentric property can be secured and respective aberrations can be excellently corrected and which can be easily manufactured. SOLUTION: This image pickup lens is constituted by arraying a 1st positive- power lens 1 whose concave surface is formed at an object side near an optical axis, a 2nd negative-power lens 2 and a 3rd positive-power lens 3 in turn from the object side. At least the 1st surface of the lens 2 positioned at the object side out of the respective lenses 1, 2 and 3 is formed to be aspherical. Then, a diaphragm 4 is disposed between the lenses 1 and 2 and arranged at the more object side than a central point between the lenses 1 and 2. Besides, a light quantity regulating plate 5 is disposed at the 1st surface side of the lens 1e Then, a CCD being as the imaging device is mounted at the 2nd surface side of the lens 3 so that the image pickup surface 6 of the CCD is formed.
