WZN3004 30 mm Dia. Zinc Selenide Standard Round Window; t=4mm AR 10600nm

The WZN3004 is a 30 mm diameter Zinc Selenide (ZnSe) standard round window, featuring a thickness of 4mm and an anti-reflective (AR) coating optimized for a wavelength of 10600nm. This window is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The window is designed as a flat window, which is a type of optical window that does not alter the wavefront of the light passing through it. This makes it ideal for applications where preserving the integrity of the light's path is crucial. The window's base shape is circular, adding to its versatility in various optical systems.

The WZN3004 is made of Zinc Selenide, a material with a wide transmission range from the UV to the mid-infrared. This makes it suitable for applications in the 10600nm wavelength range, as indicated by its coating. The window features an anti-reflective coating on both the front and back surfaces, further enhancing its performance in this wavelength range. This coating reduces reflections, increasing the amount of light transmitted through the window and improving the overall efficiency of the optical system.

The window is shaped as a thin lens, indicating that it has been precisely ground and polished to a specific curvature. This shape allows the window to focus or collimate light, making it suitable for use in imaging systems or laser applications.
