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 1):
A four-piece infrared single wavelength projection lens system, in order from an image side to an image source side, comprising:\n a stop; a first lens element with a positive refractive power, having an image-side surface being convex near an optical axis, at least one of the image-side surface and an image source-side surface of the first lens element being aspheric, the first lens element being made of glass; 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, at least one of the image-side surface and the image source-side surface of the second lens element being aspheric; 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, at least one of the image-side surface and the image source-side surface of the third lens element being aspheric; 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, at least one of the image-side surface and the image source-side surface of the fourth lens element being aspheric.
