PerfectLens L240 Aspherical
Description
Archer OpTx molded lenses are produced using the PerfectLens™ technology platform. This proprietary technology produces high-yield long-life molds, which are free of the high-frequency surface defects commonly found on many molded lenses due to single-point diamond turning of the molds. These high-frequency defects do not typically show up on interferograms, but can produce troublesome diffraction effects, particularly in visible light applications.
