The 5801 Beam Pick-Off Optic is ideal for applications where you want to monitor your laser beam, whatever the wavelength. Because the 1.0 inch (25.4 mm) diameter wedge uses simple Fresnel reflection rather than a dielectric coating, it operates over a wide wavelength range. And you can vary the pick-off amount by changing the angle of incidence. Unlike commonly used optic flats, the wedge prevents interference from the front and back surfaces.

5801光束分离光学是理想的应用程序，你想监测你的激光束，无论波长。因为1.0英寸(25.4 mm)直径的楔形采用简单的菲涅尔反射，而不是介质涂层，所以它的工作波长范围很广。你可以通过改变入射角来改变取样量。与通常使用的光学平面不同，楔形可以防止来自前表面和后表面的干扰。
