68-157 12.7 mm Dia. Sapphire Protective Flat Window; t=3.18 mm Uncoated

The 68-157 12.7 mm Dia. Sapphire Protective Flat Window is a high-quality optical component sourced from Edmund Optics. This window, with a base shape of a circle, is designed for general-purpose use and features a diameter of 12.7 mm and a thickness of 3.18 mm, making it a versatile choice for various applications.

The window is made of Sapphire (al2o3 mal-1972-n-o), a material known for its exceptional hardness, chemical resistance, and thermal stability. These properties make it an ideal choice for protective windows exposed to harsh environments. The window is uncoated, which means it does not have any additional layers to alter its optical properties. This can be beneficial in applications where the natural properties of sapphire are desired.

The window is designed to operate at a wavelength of 587.6 nm, which is within the visible light spectrum. This makes it suitable for applications where light transmission within the visible range is required. The window is shaped as a thin lens, which means it has minimal optical power and is primarily used for protecting other optical components or for transmitting light without significant refraction.
