Product description

Combining optimum grade mono-crystalline germanium, high-quality optical finishing, robust anti-reflection (AR) coating, and high-reliability transducer bonding, with novel acoustic management and optomechanical design techniques, we have successfully achieved exceptional thermal management whilst maintaining high RF power handling, transmission, and diffraction efficiency.

This modulator is ideal for extra-cavity modulation or power control of high-power CO₂ lasers.
