68-522 12.5 mm Dia. Silicon Protective Flat Window; t=2 mm Uncoated

The 68-522 is a circular, flat window made from silicon with a diameter of 12.5 mm and a thickness of 2 mm. This uncoated window is sourced from Edmund Optics, a reputable vendor in the optical industry. It is currently in stock and available for purchase through their website.

As a window, this component is designed to protect optical surfaces from environmental hazards such as dust, dirt, and moisture, while minimally affecting the light path. Its thin lens shape ensures a compact design, making it suitable for applications where space is a constraint.

The window is made of silicon, specifically silicon sal vil 1957, which is known for its excellent mechanical and thermal properties. This makes it an ideal choice for applications that require high stability and durability.

The window is designed to work with a wavelength of 587.6 nm, which is in the yellow-green region of the visible light spectrum. This makes it suitable for applications that use light in this region, such as certain types of fluorescence microscopy or specific types of laser applications.

Please note that the window is uncoated, meaning it does not have any anti-reflective or other types of coatings. This may result in some reflective loss at the air-silicon interface, which could be a consideration for applications where high transmission is critical.
