The precision polishing of bismuth silicate and bismuth germanate

A recipe is given for the polishing of precise surfaces oncrystals of bismuth silicate (BSO) and bismuth germanate(BGO). Using this recipe, crystals having surface figure betterthan 1/10 wave, roughness of 20-50 Å rms, and laserquality parallelism (10 arcsec or better) were obtained withabout 1-2 ho...

Zusammenfassung:A recipe is given for the polishing of precise surfaces oncrystals of bismuth silicate (BSO) and bismuth germanate(BGO). Using this recipe, crystals having surface figure betterthan 1/10 wave, roughness of 20-50 Å rms, and laserquality parallelism (10 arcsec or better) were obtained withabout 1-2 hours effort.
