68-490 10 mm Dia. Zinc Selenide Protective Flat Window; t=1.5 mm Uncoated

The 68-490 is a 10 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 1.5 mm, sourced from Edmund Optics. This window is uncoated, providing users with a versatile and cost-effective solution for their optical needs.

As a flat window, the 68-490 is designed to protect optical components from environmental hazards, such as dust, moisture, or physical impact, without introducing any chromatic or spherical aberrations. Its 10 mm diameter makes it suitable for a wide range of applications, from imaging systems to beam delivery and manipulation setups.

The window is made of Zinc Selenide, a material known for its excellent optical properties, including high transparency in the infrared region and a relatively low refractive index. This makes the 68-490 an ideal choice for applications that involve infrared radiation, such as thermal imaging or laser-based systems.

The 1.5 mm thickness of the window provides a good balance between mechanical strength and optical performance. It is thin enough to minimize optical distortions and light loss due to reflection, yet thick enough to withstand moderate mechanical stress.

The uncoated version of the 68-490 is a cost-effective solution for applications where high transmission and low reflectivity are not critical. However, for applications that require higher transmission and lower reflectivity, Edmund Optics offers various coating options that can be applied to the window upon request.
