The variable laser attenuators va are designed for precise precision adjustment and stabilization of laser powers.
The unit is driven by a stepper motor and can be controlled manually or by a computer.
Laser beam attenuators our laser beam attenuators provide high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction.
The newly developed laser attenuator allows computer controlled attenuation of a monochromatic light source from 1 99 see figure 1 within the wavelength region 550 nm to 1000 nm.
They provide the highest degree of reproducibility for laser processes.
This is accomplished by first rotating an incoming linearly polarized beam using a half wave plate in a rotation mount.
