Laser Attenuator
Delta Optical Thin Film A/SRequest Info
Delta Optical Thin Film AS has announced a laser attenuator with an ultra-hard-coated laser optical multilayer attenuator filter.
The laser attenuator enables computer-controlled attenuation of a monochromatic light source from 1 to 99 percent within the wavelength region of 550 to 1000 nm. It provides users with safe, repeatable, real-time control over the attenuation by combining the filter with a linear drive, controlled electronics and dedicated software.
The device is USB-controlled and features a small design. There is no pulse broadening, even with femtosecond lasers. The position of the edge of the wavelength can be adjusted by sliding the filter with respect to incident light, enabling control of the intensity or power of the transmitted laser beam.
