- Collimate or Focus Light with a Single Element
This Aspheric lens focuses or collimates light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents a single spherical lens from achieving diffraction limited performance when focusing or collimating light. Thus, an aspheric lens is often the best single element solution for many applications including collimating the output of a fiber or laser diode, coupling light into a fiber, spatial filtering, or imaging light onto a detector. This molded glass asphere is premounted in a non-magnetic 303 stainless steel len cell that is engraved with the part number for easy identification. This mounted asphere has a metric thread that makes it easy to integrate into an optical setup or OEM application.
