Discover your new PerfectLens™
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.
PerfectLens™ molds support a wide range of optical glass, providing the lens designer with the freedom to select the glass that is best suited to the application.
Archer OpTx offers precision molded aspheres in a variety of diameters from a few millimeters to several tens of millimeters in diameter. These aspheres are manufactured by pressing glass preforms in carefully prepared molds. Hard molds have a typical lifetime of tens of thousands of parts (size dependent) and are cost-effective for volumes of 200-1000+ (depending upon the size of the part).
Typical peak-to-valley figure errors (irregularity) are less than 0.5 µm. Center thickness and diameter control of 30 µm are typical. Manufacturability is determined by local radii and tooling limitations as well as the flow properties of the glass, which is quite viscous.
Precision molded aspheres are the ideal
· Medium to large volumes of the same lens
