Product description
The AOMO 3175-1999 provides controlled modulation for UV and violet laser systems where compact beam handling, fast optical response and repeatable switching performance are required. Its Crystalline Quartz AO medium supports robust short-wavelength beam interaction, making it well suited to demanding laser and photonics applications.
This modulator is designed for systems where precise beam gating, optical switching and intensity control are required in a compact optical layout. Low insertion loss, low surface reflectivity, high contrast performance and a small square aperture support clean beam control in UV laser processing, microscopy, fluorescence excitation, analytical instrumentation, optical test platforms and scientific laser systems.
