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.

 101 East Gloucester Pike Barrington, NJ 08007 United States |  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. See us at LASER World of Photonics 2023 in Munich, June 27–30 (booth B1.415)! |
