Ge Window

At TC Optics germanium window suppliers, you can expect superior performance, reliability and longevity - all at an unbeatable price point. Germanium (Ge) is in the range of 2-12 μm. Germanium is the most commonly used for making optical lenses and optical windows in high-efficiency infrared imaging systems. Due to the wide transmission range and opacity of visible light, Germanium is very suitable for infrared lasers and optical systems for the manufacture of optical components. Germanium's high refractive index and minimal surface curvature make it an ideal material for making low-power imaging systems.

Specification of Ge Window

Germanium (Ge) windows are widely used in a variety of scientific and industrial applications due to their excellent optical properties, particularly in the infrared (IR) region. Germanium has a high refractive index and a low absorption coefficient in the mid-IR range, making it an ideal material for use in IR spectroscopy and imaging applications. Germanium windows are also used in high-power laser systems and as protective windows for thermal imaging cameras.

Germanium IR windowis a type of infrared window made from Germanium material. It is transparent to long-wave infrared radiation and has a high refractive index, making it ideal for use in infrared optics. Germanium IR window can transmit light in the wavelength range of 2-16 µm, which is in the far-infrared to mid-infrared region. This transparency property makes it ideal for use in infrared imaging systems, as well as in spectroscopy and remote sensing devices. Germanium IR window can be used in harsh environments, as it is highly resistant to thermal or mechanical shock due to its high thermal conductivity. Overall, Germanium IR window is a versatile material with excellent optical, thermal and mechanical properties, making it an ideal choice for a wide range of infrared applications.

Properties and Characteristics of Germanium Windows

Optical Properties (germanium windowtransmission)

Germanium windows have a high refractive index of about 4.0 and a low absorption coefficient in the mid-IR range, making them an ideal material for use in IR spectroscopy and imaging applications. They have a broad transmission range from 2-16 μm and are particularly useful in the 2-12 μm range.

Germanium windows have high transmittance in the infrared region, particularly in the 2-16 µm wavelength range. Their transmission rate reaches up to 70% at 2 µm, 50% at 4 µm, 27% at 8 µm and 14% at 12 µm. Germanium windows are commonly used in thermal imaging applications, as well as in infrared spectroscopy and remote sensing systems. They are well-suited for use in applications that require high thermal resistance and high refractive index in the infrared region.

Physical Properties

Germanium windows are a relatively soft material with a Knoop hardness of about 780. They have a density of 5.33 g/cm3 and a thermal conductivity of about 59 W/mK, making them thermally conductive and resistant to thermal shock.

Applications of Germanium Windows

Infrared Spectroscopy and Imaging

Germanium windows are commonly used in infrared spectroscopy and imaging applications due to their high transmittance in the mid-IR range. They are often used in Fourier transform infrared (FTIR) spectrometers, where they are used as beamsplitters or as windows for sample chambers.

High-Power Laser Systems

Germanium windows are also used in high-power laser systems, where they are used as protective windows or lenses due to their high thermal conductivity and low absorption coefficient in the visible and near-IR range.

Thermal Imaging Cameras

Germanium windows are used as protective windows in thermal imaging cameras, where they are used to protect the sensitive infrared detector from dust and other contaminants while allowing infrared radiation to pass through.

Handling and Maintenance of Germanium Windows

Germanium windows should be handled with care to avoid scratching or other damage to the surface. They can be cleaned using a mild detergent and water solution or with isopropyl alcohol. It is important to use a soft, lint-free cloth or a lens cleaning tissue to avoid scratching the surface.
