When handling optics, one should always wear gloves. This is especially true when working with germanium, as dust from the material is hazardous. For your safety, please follow all proper precautions, including wearing gloves when handling this material and thoroughly washing your hands afterward.

Thorlabs' high-performance -E3 broadband AR coating has an average reflectance of less than 1.0% (per surface) across its specified wavelength range (denoted by the shaded blue area in the Coating graph below). The AR coating provides good performance for angles of incidence (AOI) between 0° and 30° (0.5 NA). The substrate transmission graph below shows the transmission of light through an uncoated Ge substrate. Please contact Tech Support to order optics with custom coatings or sizes.

The third root of any number is known as the cube root. (i.e.,) 3√ 8 = 3√2x2x2, which means, 2 is the cube root of 8. It can also be defined as a number multiplied with its square. Here is a list of both perfect and imperfect cube roots of all numbers from 701 to 800.

Thorlabs offers Ø1/2" and Ø1" wedged germanium (Ge) windows that are uncoated or AR-coated for 7 - 12 µm. These wedged optics eliminate fringe patterns and can be used to help avoid cavity feedback. Windows are useful for protecting a laser output from environmental effects and for beam sampling applications.

In addition to the germanium wedged windows offered here, Thorlabs also offers wedged windows with other substrate materials (see the selection guide above and to the right). Wedged Laser Windows with AR coatings centered around common lasing wavelengths and wedged Beam Samplers with broadband AR coatings on only one face are also available. Additionally, wedged windows with our standard AR coatings or custom sizes and thicknesses are available; please contact Tech Support for more information. We also supply planar windows with a variety of substrate materials and coating options.

Due to its broad transmission range (2.0 - 16 µm) and opacity in the visible portion of the spectrum, germanium is well suited for IR laser applications. As shown in the Graphs tab, this substrate also acts as a longpass filter for wavelengths greater than 2 µm. In addition, germanium is inert to air, water, alkalis, and acids (except nitric acid). Germanium's transmission properties are highly temperature sensitive; in fact, the absorption becomes so large the material is nearly opaque at 100 °C and completely non-transmissive at 200 °C.
