Abstract:
A four-piece infrared single wavelength projection lens system in accordance with the present invention comprises, in order from an image side to an image source side: a stop; a first lens element with a positive refractive power having an image-side surface being convex near an optical axis, the first lens element is made of glass material; a second lens element with a refractive power having an image-side surface being convex near the optical axis and an image source-side surface being concave near the optical axis; a third lens element with a negative refractive power having an image-side surface being concave near the optical axis and an image source-side surface being concave near the optical axis; and a fourth lens element with a positive refractive power having an image-side surface being concave near the optical axis and an image source-side surface being convex near the optical axis.

Claim (Index 8):
The four-piece infrared single wavelength projection lens system as claimed in  claim 1 , wherein a focal length of the second lens element is f2, a focal length of the fourth lens element is f4, and they satisfy the relation: \u22122.5<f2/f4<29.8.
