LBTEK acousto-optic modulators, operating under Bragg diffraction, produce only first-order diffracted light and transmitted light. They can function as optical switches (cycling the light on and off at a set frequency) or variable attenuators (dynamically controlling the intensity of the transmitted or first-order diffracted light). These devices are widely used in fields such as laser marking, lithography, material processing, medical surgery, and micromachining. LBTEK offers both free-space and fiber-coupled acousto-optic modulators, allowing customers to choose based on their application needs. Matching RF drivers are also provided; by inputting different modulation signals, the drivers can generate specific waveforms for flexible control.
The LBTEK programmable DC power supply is compatible with 100V/120V/220V/230V input voltages and offers a resolution of 10 mV and 10 mA. With excellent setting and readback accuracy, it ensures precise and clean output, accurately simulating even very small changes in voltage or current. Channels CH1 and CH2 can be connected in series or in parallel, extending the power output range. The power supply provides five groups of local system parameter storage, allowing users to store, recall, and delete settings in the local memory, making it easy to return to the required configurations.
