The I-M041-3C2V5-4-IS8 from Sintec Optronics is an Acousto-Optic Modulator (AOM) that operates at a frequency of 40.68 MHz and a wavelength of 2000 nm. It has a Tellurium Dioxide active aperture that measures 3 mm and has a rise/fall time of 153 ns/mm. This AOM can be controlled with an RF Driver that provides the electronic signal for the operation. With a digital driver, an external TTL signal enables rapid on and off switching of the optical beam and an analogue driver enables a variable intensity output, typically from 0% to 85% of the input beam. It is ideal for pre-press (putting image and text data onto films or plates as part of the printing process), laser imaging and displays, switching in telecom fibers, instrumentation and research.
