Description
1550nm 80MHz 0.5mm Free Space Acousto-optic Modulator for Light Optical Switch. The 1550nm free space Acousto-Optic Modulator (AOM) is used to control 1550nm laser beam intensity, frequency modulation, frequency shifting, control pulses.
The free space acousto optic modulator means the AOM is not fiber coupled. The laser runs into the AOM directly in space, but not through the fiber.
Application:
light switch
