Due to material supply chain disruptions with germanium, there may be increased lead times and price changes on our germanium products. For more information, please contact our customer service team.
Edmund Optics has limited remaining inventory of this part number and no raw material available to supply more once this is depleted. Please contact our Product Support Engineers to help with an alternate solution for your needs. Customer Service can provide you the latest price and availability.

ISP Optics Germanium (Ge) Plano-Convex (PCX) Lenses provide transmission and low absorption through the Long-Wave Infrared (LWIR) spectrum, making them useful for thermal imaging applications. Germanium is chemically inert and insoluble in water with a Knoop Hardness of 780, making it ideal for applications requiring rugged optics. However, Germanium is subject to thermal runaway and should be used at temperatures below 100°C. ISP Optics Germanium (Ge) Plano-Convex (PCX) Lenses are available uncoated with a broad transmission range from 2 – 16µm or with a Broadband Anti-Reflection (BBAR) coating for enhanced transmission in the Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR).
