Mirrors

Mirrors

  • Optical mirrors are used to reflect laser and imaging beams in applications such as beam steering, interferometry, and illumination.
  • OptoSigma offers a broad range of mirrors for use in medical, metrology, semiconductor, and scientific systems, including options with ultralow loss, high flatness, and dispersion control.
    Custom mirrors are also available to meet specific optical requirements.
