The SI-W-25.4-6 is a circular, flat window type optical element with a diameter of 25.4 mm and a thickness of 6 mm. This window is sourced from Alkor Technologies, a reputable vendor in the optical industry. The material used in the construction of this window is silicon, specifically identified as "silicon sal vil 1957".
The window is designed in a thin lens shape, making it suitable for a wide range of optical applications. The wavelength of this window is 633 nm, which is typically used in red laser applications.
Notably, this window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in certain applications where a specific coating is not required or desired. However, it's important to note that uncoated windows may have different optical properties compared to coated windows.
