WGE2504 25 mm Dia. Germanium Round Window; t=4mm Uncoated

The WGE2504 is a 25 mm diameter Germanium round window with a thickness of 4 mm, sourced from Knight Optical. This optical window is uncoated, providing users with a bare germanium surface that can be utilized in various applications.

As a window, this component is designed to allow the transmission of light or other electromagnetic radiation while providing protection for the optical system or sensor behind it. The WGE2504, in particular, is a flat window, ensuring that there is no curvature or distortion introduced to the beam path. Its circular base shape further contributes to its ease of integration in various setups.

The WGE2504 is made of germanium, a material well-known for its wide transparency range, extending from the visible spectrum to the mid-infrared region. Specifically, this window is designed for a wavelength of 10600 nm, making it suitable for use in applications that utilize this wavelength, such as certain types of spectroscopy or laser-based systems.

This window features a thin lens shape, which means it has parallel faces that minimize reflection and scattering, thereby improving transmission efficiency. The uncoated nature of this window means that it does not have any additional layers to enhance its properties, but it can be a good choice when users want to avoid potential coating-related issues, such as damage from high laser power or thermal effects.
