Electro-Optic Modulation Electro-Optic Modulator (EOM)
The Electro-Optic Modulator is a phase modulator for a variety of modulation frequencies between 3 and 25 MHz. The 6.25MHz, 12.5MHz and the 25 MHz frequencies are specifically designed for use with the TOPTICA Photonics Digilock Module. The Electro-Optic 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:
The standard characteristics are described in the Factfile tab of the table below.
The variable characteristics are listed in the Options tab.
Due to the numerous product options, please contact us for a quotation for the specific product you require.
Set up options include:
- Frequency range – from 3 to 25 MHz
- Laser wavelength range from 400 – 1500 nm with AR coating on the crystals
- MgO crystals for higher damage threshold
