Good condenser lens!
James H.•July 30, 2017
I bought these as condenser lenses for projection test rig. They are excellent with an led source. I was collimating through a test pattern on film, followed by a Canon camera lens. The test pattern was very evenly lit and sharp across the image. I am going to be ordering 20 pieces of the 30x16mm fl lenses.
