Request InfoAgiltron Inc.The all-solid-state SS series variable optical attenuators (VOAs) manufactured by Agiltron Inc. achieve response times of <100 µs. They are suitable for continuous power regulation operation, optical transient suppression and analog signal modulation applications. Electrical control of optical power via a nonmechanical configuration is activated by a low-voltage control signal. No special circuitry is required, and the design is free of mechanical movement and organic materials. The attenuators are available in normally open or normally closed configurations, and with an integrated...See full productRelated content from Photonics MediaWEBINARSPhotonics.com 6/2/2022Advances in LED Illumination for Fluorescence ImagingLED illumination for fluorescence microscopy systems has progressed significantly from a time when LED sources had low optical power and a limited range of wavelengths.
