Germanium Windows, Uncoated, 2.0 μm-16.0 μm — Model OW2-Ge

Operating wavelength 2.0 μm-16.0 μm, Ø25.4 mm, substrate Ge.

Product Description

Optical Material: Germanium
Wavelength Range: 2.0 μm -16.0 μm

LBTEK offers standard uncoated Germanium (Ge) high-precision windows. These uncoated windows operate within a wavelength range from 2.0 μm to 16.0 μm, exhibiting high transmittance across the entire spectral band. For details, see the transmittance curve. Due to Germanium's broad infrared transmission spectrum, it is highly suitable for infrared laser applications. Germanium's opacity in the visible light spectrum also allows it to function as a long-pass filter, transmitting wavelengths above 2.0 μm. The spectral transmittance of Germanium is highly sensitive to temperature. At an ambient temperature of 100°C, the material's absorption increases significantly, becoming nearly opaque, and at 200°C, it becomes completely opaque. Safety Notice: Germanium contains hazardous substances. While operation, wear gloves, a particulate-filtering respirator, chemical safety goggles, and impermeable protective clothing. Wash hands thoroughly after operation.

Germanium Windows, Uncoated, 2.0 μm-16.0 μm

Substrate Material: Germanium
Operating Wavelength: 2.0 μm -16.0 μm

The spectral transmittance of germanium is highly sensitive to temperature; at an ambient temperature of 100°C, the material's absorption becomes so significant that it is nearly opaque, and it becomes completely opaque at 200°C. Germanium material contains hazardous substances. While operation, it is necessary to wear gloves, a filtering dust mask, chemical safety goggles, and anti-infiltration work cloths. Additionally, hands should be washed after operation. All LBTEK circular lenses can be mounted in LBTEK standard lens sleeves, fixed lens holders, and various coaxial mounting plates. Customers can choose the optimal mounting method for different application scenarios.
