45-311 25 mm Dia. UVFS Round Protective Flat Window; t=2 mm Uncoated

The 45-311 is a 25 mm diameter Uncoated UVFS Round Protective Flat Window, sourced from the reputable optical components vendor, Edmund Optics. This window is a prime example of a Flat Window, characterized by its Base Shape, and is designed to provide reliable protection for optical systems while minimally affecting the path of light.

The window boasts a circular geometry with a 25 mm diameter and a thickness of 2 mm, ensuring adequate robustness without adding unnecessary weight. Its material composition, UVFS (Mal-1965), is specifically tailored for use in ultraviolet, visible, and shortwave infrared spectral regions, making it a versatile component for a wide range of optical applications.

The 45-311 window is uncoated, meaning it does not have any anti-reflective or other surface coatings. This results in a more cost-effective solution, while still delivering excellent optical quality. The uncoated nature of the window ensures high transmission at the specified central wavelength of 587.6 nm.
