39-292 100 mm Dia. UVFS Round Protective Flat Window; t=8 mm Uncoated

The 39-292 is a 100 mm diameter Uncoated UVFS Round Protective Flat Window, sourced from the renowned optical components vendor, Edmund Optics. This window is designed to protect optical systems from environmental hazards while minimally affecting the system's optical properties.

The window is made of UVFS (UV Fused Silica), a material with a high transmission range, making it suitable for a wide spectrum of applications, including UV, visible, and near-infrared light. The UVFS material, also known as Mal-1965, has a wavelength of 587.6 nm, which falls within the visible light spectrum.

The window features a flat base shape, ensuring no additional optical distortions are introduced. Its geometry includes a diameter of 100 mm and a thickness of 8 mm, providing a robust yet compact design. The window's shape is that of a thin lens, further minimizing its impact on the overall optical system.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other coatings. While this may result in higher reflective losses compared to coated windows, it also means the window is less susceptible to environmental conditions that could degrade coating performance.
