68-518 25 mm Dia. Zinc Selenide Protective Flat Window; t=2mm BBAR 8-12µm
The 68-518 is a 25 mm diameter Zinc Selenide (ZnSe) Protective Flat Window, with a thickness of 2mm, designed for use in optical systems. This window is sourced from Edmund Optics and is available for purchase online, with the weblink provided in the item data indicating its current availability.
The window is made from ZnSe, a material with the Material ID 'znse connolly'. This material is chosen for its specific properties, which make it suitable for use in optical systems. The window is coated with a BBAR (Broadband Anti-Reflection) coating, which has been applied to both the front and back surfaces. This coating is designed to reduce reflection and increase transmission across the wavelength range of 8-12µm.
The window is in the shape of a thin lens, with a base shape of a circle. The circular geometry of the window is defined by a diameter of 25mm and a thickness of 2mm. This thin lens shape is often used in optical systems to minimize aberrations and distortions.
