Where to Buy Variable Optical Attenuators

Some applications, for example in optical fiber communications, need variable optical attenuators. There are both bulk-optical (free-space) attenuators and fiber-optic devices, based on different operation principles. They can vary in terms of polarization dependence, range and accuracy of attenuation, range of operation wavelengths, power handling capability and other properties.

variable optical attenuators

Edmund Optics offers EO motorized attenuators where s-polarized and p-polarized beams are separated with a rotating quartz λ/2 waveplate. Varying the rotation of the waveplate changes the intensity ratio of the two beams without causing energy fluctuations. These attenuators are mounted with a high contrast polarizer allowing for better than 3000:1 contrast (Tp:Ts). EO motorized attenuators feature an intuitive software interface and compact design, simplifying system integration for precise remote control of laser intensity.

variable optical attenuators

LASEROPTIK can provide coatings for variable optical attenuators. One can change the transmission by tilting an edge filter, with highest transmission at normal incidence and typical operation for angles of incidence between 0° and 45°.
