Optical Modulators
Free Space Acousto-Optic Modulators/Shifter UV 111MHz
The AOMS series fiberoptic acousto-optic modulators enable high-speed optical intensity modulation optimized for UV wavelengths. Built with high-purity quartz, they feature low insertion loss, a high UV damage threshold, and fast switching. When driven at the 111 MHz resonance frequency, the device satisfies the Bragg diffraction condition, deflecting light at a specific angle. Intensity is controlled by varying the RF drive amplitude (0–5 V via SMA input). The modulator inherently introduces a positive frequency shift, with negative shift versions available upon request. It operates over a narrow wavelength range, with the output angle dependent on the input wavelength. A matching driver is available.

System integration
Integration and compatibility
Use these checks to connect Free Space Acousto-Optic Modulators/Shifter UV 111MHz to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Wavelength and loss budget
- Wavelength: 244-250nm, 300-350nm, 480-530nm, 1030-1610nm
- Check the Optical Modulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
- Control interface
- Driver: No, Yes
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
