The 68-493 is a 25 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 3 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry.
As a flat window, this component is designed to protect optical surfaces from damage, while minimally affecting the light path. Its base shape is circular, making it suitable for a wide range of applications. The window's geometry, with a diameter of 25 mm and a thickness of 3 mm, provides a robust and stable platform for optical systems.
The material of this window is Zinc Selenide, identified by the Material ID "znse marple-1964". Zinc Selenide is a popular material in optical systems due to its excellent transmission properties in the infrared region of the spectrum. The window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The window is designed to operate at a wavelength of 587.6 nm, which is in the visible light spectrum. This makes it suitable for applications that require visibility, such as microscopy or imaging systems.
In terms of shape, the window is thin and lens-like, which can help to reduce weight and simplify alignment in optical systems. The uncoated nature of the window means that it does not introduce any additional chromatic aberration or reflective losses into the system.
