| \\ The substrate must be 1" in diameter and pass >96% light from 0.5 micron to 2.45 microns. The optical surfaces must be Lambda/8 or better at 632nm, at least 5mm thick. The thickness must be matched to 0.2mm or better. An example substrate would be the Thorlabs Magnesium Fluoride Window WG61050. These substrates could be vendor supplied or supplied by CHARA to the vendor.\\ \\ Each optic would have a long pass dichroic surface on one side with >50% reflectivity from 0.45 to 0.5 microns, and would pass >96% from 0.55 to 2.45 microns. We also desire as much light as possible between 0.5 and 0.55 microns also pass through the optic. The other side would be anti-reflection coated, ideally for 0.5-2.45 microns but 0.6-2.45 microns is acceptable.\\ | \\ The substrate must be 1" in diameter and pass >96% light from 0.5 micron to 2.45 microns.
