This is a ZnSe-W-25.4-1 Flat Window, a high-quality optical component sourced from Alkor Technologies. The window, which features a base shape of a circle, has a diameter of 25.4 mm and a thickness of 1 mm, making it a thin and lightweight option for various optical applications.
The window is made of ZnSe (Zinc Selenide), a material with the material ID znse marple-1964. This material is known for its excellent optical properties, including a high refractive index and transmission in the infrared region, specifically at 10600 nm. This makes it an ideal choice for applications that require the transmission of light in this spectral range.
The window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance the performance of optical components, an uncoated window can be beneficial in certain applications where specific coatings may interfere with the desired optical properties.
