The Electro-Optical Modulator is a phase modulator for a variety of modulation frequencies between 3 and 25 MHz. The 6.25MHz and the 12.5MHz frequencies are specifically designed for use with the TOPTICA Photonics Digilock Module. The Electro-Optical Modulator can be mounted in a standard 1 inch mirror mount.
The laser wavelength range can also vary between 400-700nm, 650-1000nm and 1000-1500nm.
The various available products are listed in the following table:
