1 MT-A-VIS/IR/64, MT-A.5-VIS/IR/64 MT-A-VIS/IR/64, MT-A.5-VIS/IR AO MODULATOR/SHIFTER Product Overview These free space modulators are proposed with different aperture sizes and at various wavelength ranges. They have been specially designed for general purpose high speed application such as amplitude modulation. They can also be used as fixed frequency shifters or variable frequency shifters as well as a high speed but low resolution deflector. Features Large active aperture Linear polarization High diffraction efficiency Access to your operating manual Technical Specifications Parameter MT-xx MT-xx Material-Acoustic mode-velocity Optical Wavelength range (AR coated) Te [L] - 4 m/s VIS: 45nm -7 nm IR: 7nm-nm 64: 9nm- nm TECHNICAL DATA SHEET 4 Optical Transmission > 95 % Input / Output Polarization Active Aperture Linear / Linear x mm² or.5 x mm² Carrier Frequency / Frequency shift +/- MHz +/- MHz Separation Angle (-).3 64 nm nm Static Extinction Ratio Rise / Fall time Diffraction Efficiency Analog Amplitude modulation bandwidth (-3 db) Max optical power density (CW) Input impedance > 33 db 6 ns / mm > 5 %, nom 9 % with TEM laser beam MHz, with.3 mm beam diameter VIS: 5 W/mm² IR/64: > W/mm² Nom 5 Ω V.S.W.R.
