43-400-000 0.5 in Dia. UVFS Single Surface Flat Window; t=0.13 in Uncoated

The 43-400-000 0.5 in Dia. UVFS Single Surface Flat Window is a high-quality optical component sourced from Edmund Optics. This window, with a diameter of 12.7 mm, is designed for use in a variety of optical systems, particularly those operating at or near the visible light spectrum, with a central wavelength of 587.6 nm.

The window is made from UVFS (UV Fused Silica), a material with a wide transmission range, making it suitable for use in ultraviolet (UV), visible, and near-infrared (NIR) applications. The UVFS material is identified as "UVFS mal- 1965" in the item data, indicating its specific composition and properties.

The window features a single surface design, which simplifies its integration into optical systems and reduces the potential for unwanted reflections. The thickness of the window is 0.13 in (3.302 mm), providing a good balance between mechanical strength and optical performance.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated surfaces can reflect up to 4% of incident light, which may impact the performance of some optical systems.
