Acoustooptic modulator driver

Acoustooptic modulator driver (hereinafter referred as driver) is designed to power an acoustooptic modulator (central AOM) type AOM-80\40-1.5 (or a similar) with high frequency voltage with dual amplitude modulation (on, off) binary signal.

High stability of the carrier frequency is ensured by an integrated master generator with crystal frequency control.

The driver has built-in overheat and load mismatch protection.

The AOM must be connected to an external 15V power supply.

Code: EOMDRV-1
