47-834 30 mm Dia. UVFS Round Protective Flat Window; t=4 mm Uncoated

The 47-834 is a 30 mm diameter, 4 mm thick uncoated flat window made from UVFS material, sourced from Edmund Optics. This window is designed to protect optical systems from environmental hazards while minimally affecting the light path. The uncoated surface ensures high transmission across a wide range of wavelengths, making it suitable for various applications.

The window's geometry is defined by a 30 mm diameter and a 4 mm thickness, providing a robust and stable platform for optical systems. The flat shape ensures minimal distortion, making it ideal for applications requiring high-precision imaging. The window is designed in the shape of a thin lens, further enhancing its optical performance.

The UVFS material, identified as UVFS Mal-1965, is a high-quality fused silica known for its excellent optical properties. It has a low coefficient of thermal expansion, making it resistant to thermal shock and dimensional changes over a wide temperature range. This material also has a high laser-induced damage threshold, making it suitable for high-power laser applications.

The window is designed for use at a wavelength of 587.6 nm, but its high transmission across a broad spectrum makes it versatile for various applications. The uncoated surface ensures high transmission, low reflectivity, and minimal scattering, enhancing the overall performance of the optical system.
