Acousto-Optic Modulator for 532nm

Manufacturer's part number :


Manufacturer Isomet


Description :

Acousto-optic modulator M1115-FS80L-3 serie offers a Active aperture of 3x14mm with a Fused Silica crystal, this acousto-optic modulator is optimised for visible at 532nm.When aligned at the Bragg angle that correctly corresponds to the laser wavelength and RF frequency being applied, the AO modulator diffracts a portion of the beam passing through it (zero order) into an adjacent location (first order). The first order beam is normally used for most applications. The intensity of the first order light is controlled by the amplitude of the RF signal. Either digital (on-off) or analogue (video) AO modulation of the first order spot can be produced, depending on the type of driver selected.
