Variable Attenuators

Variable Attenuators from Timbercon produce precision levels of attenuation, with the added flexibility of adjustment. By using simple adjustment controls, the attenuation can be easily modified to any level required by your specific project. These devices are ideal for adjusting OEM systems in production as well as laboratory applications. These attenuators also exhibit low back reflection and good temperature stability in any application. Timbercon Variable Attenuators are available in both manual and automatic motor driven packages for a variety of light sources and wavelengths.

Timbercon's Automated Variable Optical Attenuator (AVOA) allows for precise levels of attenuation, with the flexibility of programmable control. Click here to download our AVOA brochure, or click the "Get a Quote" button above to contact a Timbercon Solutions Expert.
