68-510 50 mm Dia. Zinc Selenide Protective Flat Window; t=2 mm Uncoated

The 68-510 is a 50 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 2 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry.

As a flat window, this component is designed to protect optical surfaces from environmental hazards such as dust, dirt, and moisture, without introducing any optical aberrations. Its base shape is circular, making it suitable for a wide range of applications where a circular aperture is required.

The window is made of Zinc Selenide, a material with a Material ID of 'znse marple-1964'. Zinc Selenide is known for its excellent optical properties, including high transparency in the infrared region and a refractive index of 2.42 at 587.6 nm, the wavelength for which this window is designed.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where such coatings are not required or desirable. However, it's important to note that uncoated windows can have higher reflectivity, which may need to be taken into account in the system design.

The window is 2 mm thick, providing a good balance between strength and weight. It is classified as a thin lens, indicating that its thickness is significantly less than its diameter, which helps to minimize optical aberrations.
