43-634 22 mm Dia. Sapphire Protective Flat Window; t=1 mm Uncoated

The 43-634 is a 22 mm diameter uncoated sapphire window, designed and manufactured by Edmund Optics. This window is a flat, circular-shaped optical component, characterized by its thin lens geometry and a thickness of 1 mm.

Sapphire, or aluminum oxide (Al2O3), is the material of choice for this window due to its exceptional properties. It is highly resistant to scratching and environmental damage, making it an ideal protective layer for optical systems exposed to harsh conditions. Sapphire also boasts excellent transparency across a wide spectrum, including the visible, ultraviolet, and infrared regions, with a peak wavelength of 587.6 nm.

The window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain properties, such as reducing reflection or increasing transmission, an uncoated window is often sufficient for many applications. It is important to note that the lack of coating may result in higher reflectivity at the air-sapphire interface, but this can be mitigated with appropriate anti-reflection coatings if required.
