83-342 12.5 mm Dia. Germanium Protective Flat Window; t=3 mm Uncoated

The 83-342 is a 12.5 mm diameter Germanium Flat Window, with a thickness of 3 mm, sourced from Edmund Optics. This uncoated window is designed to protect optical components from environmental hazards while minimally affecting the light path.

Germanium, denoted as "germanium burnett" in the Material ID, is a semiconductor material known for its high refractive index and ability to transmit infrared light. This makes the 83-342 an ideal choice for applications in the infrared spectrum, such as thermal imaging and night vision devices.

The window features a circular base shape and a thin lens geometry, designed to minimize optical aberrations and distortions. The uncoated surface ensures high damage threshold and low scatter, making it suitable for high-power laser applications.

The window's parameters include a wavelength of 587.6 nm, which is in the visible light spectrum. However, Germanium's high refractive index and transmission in the infrared spectrum make it more suitable for infrared applications.
