68-497 75 mm Dia. Zinc Selenide Protective Flat Window; t=6 mm Uncoated

The 68-497 is a 75 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 6 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

As a window, this component is designed to protect optical systems from environmental hazards while minimally affecting the light path. The 75 mm diameter provides a substantial aperture, allowing for a wide range of applications. The 6 mm thickness offers a good balance between strength and light transmission, making it suitable for various optical setups.

The Zinc Selenide material (ZnSe) is a popular choice for infrared applications due to its high transmittance in this region. The uncoated version of this window does not have any additional layers, which can affect the transmission or alter the properties of the light passing through. This can be beneficial in applications where coatings may introduce unwanted reflections or absorption.

Please note that the window's wavelength is 587.6 nm, which is in the visible light spectrum. However, ZnSe's high transmittance in the infrared region makes it a versatile material for a wide range of applications, from visible light to infrared.
