The 10SI20 is an uncoated, 25.4 mm in diameter and 2.0 mm thick Silicon window. Silicon has good transmission range from 1.2 to 7.0 μm. With its low density (2.329g/cm3) silicon windows are ideal for application which are weight sensitive. With Knoop hardness value of 1100, silicon windows are more robust and less brittle than germanium window, making it a good choice for IR applications.

10SI20是一个未涂层的，直径25.4毫米，厚2.0毫米的硅窗。硅具有良好传输μm范围从1.2到7.0。低密度(2.329g/cm3)的硅窗非常适合重量敏感的应用。由于Knoop硬度值为1100，所以硅窗比锗窗更坚固、更不脆，是IR应用的好选择。
