Description

Erbium sodium phosphate glass ingot – Er3+ 34mol% NEW!

diameter ~ 30 mm – ~ 25 grams
Material: Na Er P Glas – Er3+ (~ 34mol%)
This strongly pink colored glass  is used in optics application where high levels of Er doping is needed.
We are able to cast large rods with several cm diameter and lengths up to 50mm

Beautiful optical glass beads doped with metal ions.

Elaborately and individually manufactured by us in the laboratory from highly pure reagents.
Gorgeous beads showing the typical colors of different metal ions in different oxidation states.

They can be used for save demonstration of different colors of the metal compounds or just for collecting.
