Optical System

Aspherical Microlens Array

  • Microlens array, of which glass materials superior for excellences with environment resistance and temperature properties, is actualized. It also corresponds with telcordia standard by precise molding.
  • As materials with high refractive index, K-VC89 exceeds 1.8(nd) refractive index is also available.
  • We actualize low cost and mass production(10,000 pcs per month, more than 10,000 pcs are possible) by making use of producing molding tools.
