Beam Pick-Off Optic, 1.0 in. Diameter, N-BK7

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.
