68-494 30 mm Dia. Zinc Selenide Protective Flat Window; t=3 mm Uncoated

The 68-494 is a 30 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 3 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

The window is designed as a flat window, which is a type of optical window that does not alter the path of light. It is circular in base shape, making it suitable for a wide range of applications. The window's geometry, with a diameter of 30 mm and a thickness of 3 mm, provides a robust and stable platform for optical systems.

The material of the window is Zinc Selenide, identified as 'znse marple-1964' in the Material ID. Zinc Selenide is a popular material for optical windows due to its excellent transmission properties in the infrared region of the spectrum. The window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The window is designed to work at a wavelength of 587.6 nm, which is in the visible light spectrum. It has a shape of a thin lens, which is a type of lens with a very small focal length compared to its diameter. This shape allows the window to be used in a variety of applications where a thin, flat optical surface is required.
