KTN vari-focal lens

Key Features

  • Electro-optic based varifocal lens
  • Voltage-controlled
  • High-speed focusing: 1 microsecond response

Description

The KTN vari-focal lens is the highest speed vari-focal lens in the world, with a focal length that can be varied in a matter of micro seconds.

It provides extremely fast time response, allowing easier automation because shifting the light is driven completely electronically and not using any moving mechanical parts.

A 3D image can be obtained by changing the focal-length continuously or shifting it instantly.

The KTN vari-focal lens works as a convex lens and the focal-length is varied in proportion to the square of the supplied voltage. It has been confirmed that the vari-focal lens can be applied to various fields because a voltage of 1kV can result in a focal-length shift of 4cm in a lens with f=25cm.*

Applications

  • Microscopy
  • OCT
  • Various types of experiments
  • Sensing
  • Laser processing
