Increased Measurement Efficiency Reduces Lead Times!

We invite you to attend this 30-minute webinar presented by Janet Lim, Process Engineer at Edmund Optics®, Singapore. At the end of this webinar, attendees will have a strong understanding of:

  • How computer-generated holograms (CGHs) improve efficiency of asphere measurement
  • Solutions for challenges experienced during CGH metrology
  • How CGHs can be integrated into corrective polishing processes to shorten manufacturing process time and increase precision
