Product Family Description

  • Precision Glass Molded Lenses
  • Ideal for High Volume Production Requirements
  • Available in Convenient Packs of 10 for Volume Integration

TECHSPEC® Precision Molded Aspheric Lenses are manufactured through a precision glass molding process to meet the same specifications as our polished TECHSPEC Precision Aspheric Lenses. These lenses are designed to have optimal performance when molded by accounting for the change in index of refraction that occurs during the molding process. TECHSPEC Precision Molded Aspheric Lenses eliminate spherical aberrations and can be used to replace multiple spherical elements in an optical system to simplify design, lower system weight, and decrease costs. Due to the differences between the glass molding and polishing processes, these lenses have an increased surface roughness over their polished counterparts and may produce more scatter. However, the scalable precision glass molding process is ideal for high volume OEM integration.
