Abstract
An imaging lens system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens disposed in order from an object side. One of the first to ninth lenses is a temperature compensation lens having positive refractive power and having an absolute value of a refractive index temperature coefficient of 10 (10−6/° C.) or less.
Claims16
An imaging lens system comprising:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and a ninth lens disposed in order from an object side,
- wherein one of the first to ninth lenses is a temperature compensation lens having positive refractive power and having an absolute value of a refractive index temperature coefficient of 10 (10−6/° C.) or less.
An imaging lens system comprising:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, and ninth lens, disposed in order from an object side, and a stop disposed between the first lens and the ninth lens,
- wherein 0<fstp12<f, where fstp12 is a composite focal length of two lenses continuously disposed on an image side of the stop, and f is a focal length of the imaging lens system.
