KTN Deflector


This reflector by NTT-AT can scan a laser beam for both continuous and step scanning modes by controlling voltage. The operation wavelength is in the 488-3500 nm range. The scanner chip is composed of a small KTN crystal chip with electrodes. This makes it possible to reduce the device size to 1/100 compared to moving mirrors such as polygon and galvanic mirrors.

High-speed, solid-state laser beam scanner will replace polygon mirror, galvanic scanner or MEMS.


  • Compact size (40% smaller than conventional company products).
  • Bi-direction, voltage-controlled, continuous and step scanning.
  • Scan up to 10 degrees deflection at 10k - 100kHz.
  • Wide operation wavelength range: 488 - 3500nm.
