W-SIS025 25.4 mm Dia. Silicon Infrared Flat Window; t=1mm Uncoated

The W-SIS025 is a 25.4 mm diameter Silicon Infrared Flat Window with a thickness of 1mm, uncoated and sourced from Ross Optical. This window is a type of optical element, specifically a Flat Window, designed for use in infrared applications.

The window's base shape is circular, making it suitable for a wide range of optical systems. The geometry of this window includes a diameter of 25.4 mm and a thickness of 1 mm, providing a balance between durability and light transmission.

The material of this window is Silicon, identified as "silicon sal vil 1957" in the Material ID. This material is known for its excellent transmission properties in the infrared region, making it ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired.

The wavelength of this window is 633 nm, which is in the visible light spectrum. However, due to the material and design of this window, it is most suitable for infrared applications.

The window's shape is that of a Thin Lens, which is a lens with a thickness that is small compared to its diameter. This shape helps to minimize optical aberrations and distortions, further enhancing the window's performance in optical systems.
