G390153000 40 mm UVFS Optical Flat Window; t=4mm Uncoated

The G390153000 40 mm UVFS Optical Flat Window is a high-quality optical component designed for a wide range of applications. Manufactured by Qioptiq Photonics, this window boasts a diameter of 40 mm and a thickness of 4 mm, making it a robust and reliable choice for various optical systems.

This optical window is made from UVFS, a type of fused silica known for its excellent optical properties. The UVFS material, specifically identified as "uvfs mal- 1965", ensures high transmittance across a broad spectrum, making it suitable for use in ultraviolet (UV), visible, and near-infrared (NIR) applications.

The window is of the Flat Window sub-type, which means it has a flat surface on both sides, ensuring minimal distortion and scattering of light. Its base shape is circular, a common and versatile shape in optical systems due to its symmetry and ease of alignment.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where a specific coating is not required, or where the user prefers to apply their own coating to match their specific needs.

The G390153000 40 mm UVFS Optical Flat Window is available for purchase from the Qioptiq Photonics website, where it is listed as in stock. The product's webpage provides more detailed specifications and additional technical information.
