1210-G(fc)-H (MIR)
Acousto-Optic Modulator, 2.05 - 4.0 um
APPLICATIONS
• Modulator • Frequency Shifter
The 1210 series are conduction cooled Germanium AO modulators/frequency shifters designed for operation in the 2.05 - 4um range. Input light must be linearly polarized, parallel to the mounting base.
