Ge Germanium Spherical Plano-Convex Lenses

MATERIAL - Ge (Germanium)


Crystaltechno Ltd. manufactures spherical plano-convex lenses from Germanium (Ge), other optical crystals and glasses.

Germanium (Ge) spherical plano-convex lenses are widely used as focusing optics.

Perhaps you will find the required Germanium (Ge) optics at our stock, please see item Optical Crystals.

Ge Spherical Plano-Convex Lenses PARAMETER VALUE
