Variable Laser Beam Attenuator

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.

Variable laser beam attenuator.

Showing 44 products in 4 families. The attenuator is then given by laser 1 2 wave plate polarizer p s b eam stop figure 1. Attenuators consist of thin film polarizer high performance waveplate and precision opto mechanics. They are suitable for cw lasers.

Tye are typically used for excimer and yag laser wavelengths. 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. Zero order 1 2 wave plate. We also offer laser beam attenuation kits for ultrafast laser pulses.

The electric field of a laser beam decomposes into two orthogonal components. Motorized variable attenuator for linearly polarized laser beam 990 0071m motorized variable attenuators with ø 10 mm clear aperture allowing to continuously vary the intensity ratio of exiting s pol and p pol beams. Volume pricing request a quote. These techniques do not typically allow for continuous control of the laser power.

Cos 2 q i i o 1 e v e e o f f l a s e r b e a m l a s e r p o l a r i z a t i o n e figure 2. This is accomplished by first rotating an incoming linearly polarized beam using a half wave plate in a rotation mount.

The variable laser attenuators va are designed for precise precision adjustment and stabilization of laser powers. 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. Laseroptik offers avacs automatic variable attenuator control system. Motorized rotation of the waveplate allows continuous variation of the intensity ratio of the output beams.

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. Qty 1 1 525 00. Rotation of the wave plate by angle ø. The avacs includes power supply control display operation elements starting routine limit stop device computer interface and water cooling.

Step add to. They provide the highest degree of reproducibility for laser processes. The unit is driven by a stepper motor and can be controlled manually or by a computer. Eprt iges pdf drawing step.

Our variable attenuator kit is an easy to use kit for the continuous attenuation of the laser output power.
