48-920 35 mm Dia. Sapphire Protective Flat Window; t=1 mm Uncoated

The 48-920 is a 35 mm diameter uncoated sapphire window, boasting a thickness of just 1 mm, making it an ideal choice for applications requiring minimal material interference. Sourced from the reputable vendor Edmund Optics, this window is available for immediate use, as indicated by its valid in-stock weblink status.

As a window, this component is designed to protect optical surfaces and systems from environmental hazards while minimally affecting the light path. Its flat shape ensures a uniform, distortion-free view, making it suitable for a wide range of applications.

The window is made from high-quality sapphire, a material with the chemical formula al2o3, and is identified as mal-1972-n-o in the Material ID. Sapphire is renowned for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions. It also exhibits excellent optical clarity, transmitting light efficiently across a broad spectrum, including the visible and near-infrared regions.

The window's geometry is defined by its 35 mm diameter and 1 mm thickness. This thin profile minimizes weight and potential optical distortions, making it an excellent choice for precision applications.

Notably, this window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance specific optical properties, such as reflectivity or transmission, an uncoated window offers simplicity and versatility, allowing the user to control these properties through other means.
