  • angle selective filter
  • optical thin film
  • Abstract We have designed and fabricated angle-selective filters to increase the luminous throughput of a light source system. The emission direction was tailored to increase the light emission in the useful direction by using multilayer optical coating with alternating high and low refractive indices layers.
    Thin film filters can increase the effectiveness of the spectrum shifts toward shorter wavelengths with increasing the incident angle. The displacement of the designed filter is double that of the normal low pass filter so as to conform to the broad spectrum of light source.
    The angle selective filters limit the luminance angle to less than an acceptance angle of 30 degrees for green and red light source. The filters increase the luminance efficiency by converging and recycling the light. And, the color performance of the light source was improved.
