43-367 15 mm Dia. Sapphire Protective Flat Window; t=2 mm Uncoated

The 43-367 is a circular, flat window made from high-quality sapphire, offering a 15 mm diameter aperture and a thickness of 2 mm. This window, sourced from Edmund Optics, is uncoated, providing users with a versatile and reliable optical component.

Sapphire, with the material ID al2o3 mal-1972-n-o, is a popular material for optical windows due to its excellent properties. It boasts a high Mohs hardness of 9, making it highly scratch-resistant and durable. Sapphire also features a wide transmission range, spanning from the ultraviolet (UV) to the near-infrared (NIR) regions, with a peak transmission at the visible wavelength of 587.6 nm. This broad transmission range, coupled with its robustness, makes sapphire an ideal material for protective windows in various applications.

The 43-367 window features a thin lens shape, allowing it to be easily integrated into optical systems. Its uncoated surface ensures minimal reflection, maximizing transmission and maintaining high optical performance. The window's thin lens shape and uncoated surface contribute to its versatility, making it suitable for use in applications where minimal optical interference and high durability are required.
