This is the SI-W-152.4-6, a 152.4 mm diameter Silicon Flat Window with a thickness of 6mm, uncoated. The window is sourced from Alkor Technologies, a reputable vendor in the optical industry.
The window is designed in a flat shape, which is ideal for applications that require a simple, non-refracting optical interface. The base shape of the window is circular, making it suitable for a wide range of applications where a circular aperture is required.
The material of the window is silicon, specifically silicon sal vil 1957. This material is known for its excellent optical properties, including high transparency and resistance to environmental factors. The window is designed to operate at a wavelength of 633nm, making it suitable for applications that use red light, such as in laser systems or optical spectroscopy.
The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in applications where a natural surface is required, or where the addition of a coating could introduce unwanted optical effects.
The window is available for purchase directly from Alkor Technologies, and more information about it can be found on their website. The link provided in the item data indicates that the window is currently in stock, ensuring quick delivery times for those who need it.
