39-399 50 mm Dia. Zinc Selenide Protective Flat Window; t=5 mm Uncoated

The 39-399 is a 50 mm diameter, 5 mm thick Zinc Selenide (ZnSe) protective flat window, uncoated and sourced from Edmund Optics. This window is a type of optical element, specifically a flat window, designed for use in various optical systems to protect the more sensitive components from environmental factors such as dust, moisture, or mechanical damage.

The Zinc Selenide material (ZnSe) is known for its excellent transmission properties in the infrared region, making this window suitable for applications in the near, mid, and far-infrared spectrum. The window's 5 mm thickness provides sufficient robustness while maintaining minimal optical distortion.

The uncoated nature of this window means it does not have any additional anti-reflective or other coatings. While this may result in a higher reflectivity compared to coated windows, it also ensures a broader range of compatibility with various coatings that users may wish to apply according to their specific requirements.

The window's circular base shape and thin lens geometry further contribute to its versatility, allowing it to be easily integrated into various optical systems. The window's current status is in stock, as indicated by its weblink, ensuring users of its immediate availability.
