Welcome to LASNIX



LASNIX offers since 1984 unique infrared components: free-standing metal grids to control polarization and power of laser beams up to high power. Their unique value is that - due to the missing substrate - the transmitted beam is neither offset nor deviated.

Both diffractive and sub-diffractive grids are tailored for specific applications spanning the infrared-to-THz range (0.7 - 1200 µm wavelength).

  • Step attenuation for infrared and THz beams

    The proprietary LASNIX diffraction technology enables precise attenuation over multi-octave wavelength bands. Neutral density filters and multi-step attenuators handle beam powers up to 300 W c.w. while faithfully maintaining polarization and pulse dispersion.

  • Continuously variable attenuation and defined polarization for CO2 laser beams

    A proprietary LASNIX design enables a near perfectly transmitting linear polarizer with 40 db rejection. In the continuously variable attenuator two polarizers can be set to continuously control the transmitted beam power, and independently set its polarization orientation.

  • Compact sensing of infrared beam power and polarization

    A proprietary LASNIX development of a very fast power meter up to 50 W is offered for OEM monitoring or process control. Combined with attenuation and a rotating polarizer the polarization sensor offers a compact solution to determine the polarization status (orientation, ellipticity, circularity) of even very strong beams up to 3 kW c.w.
