43-404-000 0.5 in Dia. Zerodur Single Surface Flat Window; t=0.13 in Uncoated

The 43-404-000 0.5 in Dia. Zerodur Single Surface Flat Window is a high-quality optical component sourced from Edmund Optics. This window, with a diameter of 12.7 mm, is designed for use in a variety of optical systems, particularly where precision and durability are paramount.

The window is made from Zerodur, a low-expansion glass-ceramic material developed by Schott AG. Zerodur is renowned for its exceptional dimensional stability and homogeneity, making it an ideal choice for applications requiring high precision and long-term stability. The material's low thermal expansion coefficient minimizes the impact of temperature changes on the window's shape and optical properties.

The window features a single surface flat design, ensuring excellent optical quality. The flatness of the surface is critical in applications where wavefront distortion must be minimized, such as in interferometry or high-resolution imaging systems.

The window has a thickness of 0.13 in (3.302 mm), striking a balance between robustness and light transmission. Despite its thickness, the window remains relatively lightweight, making it suitable for use in portable or handheld devices.

This particular window is uncoated, meaning it does not have any anti-reflective or other surface coatings. While coatings can enhance the performance of optical components in specific applications, an uncoated window can be advantageous in situations where environmental factors or cost considerations preclude the use of coatings.
