BK7 窗口片
窗口片的作用是在两个不同环境之间传输光辐射, 同时防止其它的环境物质的干扰介入. 窗口片不会改变光线的波长分布, 传输的波前特性, 也不会造成光线的散射.博信生产的BK7平行窗口片具有低变形, 低散射, 高平行度等优点.

The BK7 window effect is to transmit optical radiation between two different environments while preventing interference from interfering with other environmental substances. The window does not change the wavelength distribution of the light, the wavefront characteristics of the transmission, nor does it cause light scattering. Boxin produced BK7 parallel window with low deformation, low scattering, high parallelism and so on.
