Acousto-Optic Devices Acousto-Optic Tunable Filters Type: EFLF Acousto-Optic Tunable Filter uses an anisotropic diffraction of light occuring with shear-mode acoustic waves travelling in a single crystal of tellurium dioxide (TeO 2 ), which is a high speed spectral element selecting optical monochromatic light from multicolor at high speed. Features ● Low driving power (0.5 to 1.0 W) spectrum scanning (6 to 9 μs) ● Wide optical tuning range (380 to 750 nm) ● High spectrum resolution (0.4 to 2.3 nm) ● RoHS compliant ● Rapid Recommended Applications ● Rapid ● Color scan spectrum analyzer decomposition Principle Tunable Filters TeO2 crystal Absorber Incident light 2 1 1 3 2 Acoustic wave 3 Tuned light l1 Untuned light Tuned light l1+Dl f1 Oscillator Transducer Explanation of Part Numbers 1 2 3 4 E F L F Product Code 5 6 Characteristics (Resolution) 7 8 9 10 Design No. Design and specifications are each subject to change without notice.
