Projection lens is a kind of lens which transfer an image from one place to another –Magnification is generally required •Generally, projection lens is required to –Achieve sufficiently-bright image •In this case, optical throughput is key issue –Kohler illumination scheme is generally adopted –Cover a relatively wide field in a short throw distance •Therefore, high-speed (f/1 or faster) –Aberration can be more sensitive to the distance to image plane »Approach based on Macro lens is required
