A636 5422 - aspherical lens for illumination with minor structure

Lens A636 is the only lens in our portfolio with minor structure on aspherical lens side. We offer other lenses with structure such as: A850, A904 or A912, but they all have structure on the lens flat side. Lens A636 is unique with molded structure on aspherical side which guarantees a very mild defocusing while keeping maximal efficiency.
