88-429 20 mm Dia. Precision Sapphire Flat Window; t=2 mm Uncoated
The 88-429 is a 20 mm diameter precision sapphire flat window, with a thickness of 2 mm, sourced from Edmund Optics. This window is designed as a flat window, featuring a base shape of a circle, making it suitable for a wide range of applications.
The window is made of aluminum oxide, also known as sapphire, with the material ID al2o3 mal-1972-n-o. Sapphire is a highly durable and scratch-resistant material, making it an ideal choice for optical windows. It has a high transmittance across a wide range of wavelengths, including the visible spectrum, making it suitable for various applications.
The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the natural properties of the material are desired, or where the addition of a coating could interfere with the performance of the system.
The window is designed to operate at a wavelength of 587.6 nm, which falls within the visible spectrum. This makes it suitable for applications where visual clarity is important.
The window is shaped as a thin lens, which can be beneficial in applications where a flat surface is required, or where the window needs to be as thin as possible to minimize its impact on the overall system.
