532nm Space AOM  Series

An acousto-optic modulator is a kind of acousto-optic product that modulates laser intensity by acousto-optic effect and shifts its frequency. The wavelengths range from the ultraviolet to the mid-infrared. After the beam passes through the acousto-optic medium, diffraction occurs, and its frequency and intensity will be changed. The products have superior performance, such as high transmittance, diffraction efficiency, and low power consumption. Acousto-optic modulators can control speed and modulate light intensity far beyond that of mechanical shutters. Use the recommended companion drivers for optimal performance and a wider range of application options.

N-type Acousto Optic Driver

An RF driver usually consists of an RF oscillator, a modulation circuit, and a power amplifier. The RF driver generates RF signals that are used to generate sound waves within the crystals of the AO device. The frequency and strength of the RF signal will determine the degree to which the beam is modulated, deflected, or tuned. The acousto-optic driver can perform digital/analog modulation of the beam and also realize frequency shift functions. The driver has a good heat dissipation function, and the performance of the product is reliable and stable when working with the matching acousto-optic device.
