Triple-notch Filter for head-up display

Our state-of-the-art coating technology has enabled triple notch filter to be achieved with large substrate.
It reflects RGB color with arbitrary ratio and keeps high transmittance over the visible wavelength.
We can supply approximate 420mm diameter triple notch filter with excellent coating uniformity over the clear aperture for large screen of head-up display.

• Any RGB wavelength / reflectance ratio are available
• Large size of filter (Approximate 800mm diameter filter may be available by this summer)
• Excellent coating uniformity
  Actual performance of uniformity : Wavelength x 0.3% over 420mm diameter
  (e.g. 500nm x 0.003 = 1.5nm variation / pv)
