Reflectivity gold
WebREFLECTIVITY Gold is totally inert to all aqueous and organic liquids over long periods of exposure. This means that there is no loss in reflectance over time as compared to copper and silicon based mirrors. Typical reflectance for Cu/Ni/Au mirrors are as follows: 10.6um (CO2) >99.0%. 1.064nm (Nd:YAG) >98.5% 632.8nm (HeNe) >90% Weberties for welding, but its high reflectivity and high thermal conductivity makes it dif-ficult to weld at penetrations greater than 0.5 mm. silver and gold can be welded but with same limitations on penetration depth. platinum however, welds well up to ap-proximately 2mm penetration, depending upon the alloy. these metals are used for
