Abstract

A non-polarizing broadband dichroic filter with high reflectance from 400 to 600nm and high transmittance from 650 to 1000nm was designed with a simple structure and fabricated by electron-beam evaporation with ion-beam-assisted deposition (IBAD). Experimental spectral performances showed a good agreement with the theoretical curves. In addition, the designed dichroic filter can also show high transmission from 670 to 930nm with non-polarization over a wide range of incident angles.
