Advantages

  • Ultimate alignment accuracy 

The special contour of the aspherical surface can precisely compensate for the wavefront distortion of the laser beam.

  • Single-lens design, strong system integration

The lens can achieve high-precision alignment with a single lens, significantly simplifying the optical system structure.

And  it reduces the number of lenses by more than 50%.

  • Wide band adaptation

The lens can cover the mainstream laser wavelength bands from ultraviolet to infrared.

  • High damage threshold

Using high-purity optical substrates and advanced coating technology

  • Stable physical properties

The lens can adapt to complex environments such as industrial and outdoor settings.
