SAW22 23.75 mm Dia. Sapphire Parallel Optical Flat Window; t=1 mm Uncoated

The SAW22 is a high-quality optical window manufactured by MKS/Newport, a leading vendor in the field of precision optics. This window features a base shape of a circle with a diameter of 23.75 mm, making it suitable for a wide range of optical applications. The window has a thickness of 1 mm, providing a balance between durability and light transmission.

The material of this window is sapphire, specifically identified as al2o3 mal-1972-n-o in the item data. Sapphire is known for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions. It also has excellent optical properties, including a high refractive index and low absorption, which contribute to high-quality image transmission.

The window is designed for use at a wavelength of 633 nm, although it may be suitable for other wavelengths depending on the specific requirements of your application. The shape of the window is thin lens, which is optimal for applications where minimal optical distortion is required.

Notably, this window is uncoated. While coatings can enhance the performance of optical windows in specific applications, an uncoated window offers the advantage of broadband transmission and minimal reflection, making it a versatile choice for many users.
