OPZS-40C04-10-3 40 mm Dia. ZnSe Round Flat Window; t=4 mm Uncoated

The OPZS-40C04-10-3 is a 40 mm diameter Zinc Selenide (ZnSe) round flat window with a thickness of 4 mm, sourced from OptoSigma. This window is a type of optical element, specifically a flat window, designed for use in various optical systems.

The window's base shape is circular, which is a common design for optical elements due to its symmetry and ease of integration into various systems. The geometry of the window includes a diameter of 40 mm and a thickness of 4 mm, making it a substantial yet manageable size for many applications.

The material of the window is Zinc Selenide, identified in the item data as "znse marple-1964". Zinc Selenide is a popular material in optical systems due to its excellent transparency in the infrared region of the spectrum. This makes it suitable for applications that involve infrared light, such as thermal imaging or night vision systems.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in some applications where a bare surface is preferred, but it may also mean that the window is more susceptible to environmental factors such as dust, dirt, or moisture.

The window is currently in stock and available for purchase, as indicated by the "weblink status" in the item data. For more information, users are encouraged to visit the vendor's website via the provided weblink.
