39-230 25.4 x 25.4 mm Sapphire Protective Flat Window; t=1 mm Uncoated

The 39-230 25.4 x 25.4 mm Sapphire Protective Flat Window is a high-quality optical component sourced from Edmund Optics. This window, designed for protective applications, boasts a rectangular base shape with dimensions of 25.4 mm in width and length, making it suitable for a wide range of optical systems.

The window features a thickness of 1 mm, providing a balance between durability and minimizing optical distortion. It is made from Sapphire (Al2O3), a material with a Mal-1972-N-O Material ID, which is known for its exceptional hardness, chemical resistance, and transparency across a wide spectral range.

The window is uncoated, meaning it does not have any additional layers to alter its optical properties. This can be beneficial in applications where maintaining the native properties of the Sapphire material is crucial. However, it's important to note that uncoated surfaces may reflect a portion of incident light, which could be a consideration in high-precision applications.

The window is designed to operate at a wavelength of 587.6 nm, although its properties may be suitable for a broader spectral range. It is classified as a Thin Lens due to its minimal thickness relative to its aperture.
