The Archer OpTx PerfectLens® aspheric achromat is designed to support systems that require diffraction limited performance through a broader spectrum than traditional aspheric capabilities. Using these lenses, it is possible to design systems where multiple sources are collimated and/or focused by a single lens. An additional benefit to the Archer OpTx PerfectLens® aspheric achromat is that it is designed so the effective focal length is the same across the full spectrum.
