Our variable attenuator kit is an easy to use kit for the continuous attenuation of the laser output power. Volume pricing request a quote.

Qty 1 1 525 00. Step add to. The unit is driven by a stepper motor and can be controlled manually or by a computer. These techniques do not typically allow for continuous control of the laser power.

This is accomplished by first rotating an incoming linearly polarized beam using a half wave plate in a rotation mount. Zero order 1 2 wave plate. The avacs includes power supply control display operation elements starting routine limit stop device computer interface and water cooling. Motorized variable attenuator for femtosecond and nd yag laser pulses 990 0072m motorized variable attenuators with ø 22 mm clear aperture composed of thin film polarizers half waveplates and opto mechanics for easy setup.

Tye are typically used for excimer and yag laser wavelengths. They are suitable for cw lasers. Laseroptik offers avacs automatic variable attenuator control system. Eprt iges pdf drawing step.

The electric field of a laser beam decomposes into two orthogonal components. The attenuator is then given by laser 1 2 wave plate polarizer p s b eam stop figure 1. The variable laser attenuators va are designed for precise precision adjustment and stabilization of laser powers. Products lasers laser measurement and electronics laser beam analysis coherent lasercam beam profiler.

Attenuators consist of thin film polarizer high performance waveplate and precision opto mechanics. We also offer laser beam attenuation kits for ultrafast laser pulses. Rotation of the wave plate by angle ø. They provide the highest degree of reproducibility for laser processes.

To adjust the laser power down to the level required typically users are forced to use either neutral density filters or other devices to reduce the pump power going to an experiment. 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. Thorlabs variable beamsplitters allow the user to continuously vary the transmitted intensity of a linearly polarized beam of light.
