Germanium Window 30mm Diameter

OPGE-30C03-P

The Germanium as a mono crystal primarily used in semi-conductor is non-absorptive at 2μm to 20μm IR regions. It is used here as an optical component for IR region applications.
◦These germanium windows do not transmit at 1.5µm region or below, therefore its main application is in the IR regions.
◦Germanium windows can be used in various infrared experiments.

Guide
  • For transmittance at visible regions optics, we recommend to use ZnSe IR spectrum windows.
  • WEB Reference Catalog Code/W3152
  • For product sizes and wedges which are not listed on our website or in our catalog, please contact our Sales Division with your requests.
Remark -
Attention
  • Germanium windows have a shiny metal surface; it reflects and absorbs but does not transmit in the visible regions.
  • Germanium windows surface reflection results in transmittance loss of 42%. (Measured data 1 surface reflection at 35%)
