G390114000 40 mm UVFS High Parallelism Optical Flat Window; t=8mm Uncoated

The G390114000 is a high-quality optical window, specifically designed for use in applications requiring excellent UV transmission and high parallelism. Manufactured by Qioptiq Photonics, this window boasts a diameter of 40 mm and a thickness of 8 mm, making it suitable for a wide range of optical systems.

As a flat window, it is designed to provide a clear aperture for optical systems without introducing any optical power. This makes it ideal for protecting sensitive optical components or as a simple beam separator. The window's base shape is circular, a common and versatile shape in optical design.

The window is made from UVFS, a type of fused silica known for its exceptional transparency across the ultraviolet spectrum. This material is identified as UVFS Mal-1965 in the item data, indicating its specific grade and properties. The wavelength specified for this item is 633 nm, which falls within the visible light spectrum.

The window is uncoated, meaning it does not have any additional layers applied to alter its optical properties. This can be advantageous in certain applications where a natural transmission spectrum is required or where cost is a concern. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust and moisture.
