Newport 925B Compensated Attenuator

$350.00

Newport 925B Compensated Attenuator.

The 925B Compensated Attenuator provides high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction. The optical density can be varied from 0.16 to 3.0 through a top-mounted adjustment knob. It has a 1/2 inch (12.7 mm) diameter aperture. Attenuation is achieved by moving two matched BK 7 wedged filters in opposing directions. The filters have a linear-variable aluminum neutral density coating and a broadband antireflection coating. The slight wedge in the filters displaces any secondary reflections off-axis. The filters are matched for minimal beam deviation.
