Millimeter Wave Lens

Model No. MMS06

Millimeter wave lenses can convert spherical waves into plane waves, which brings sharp directivity.

KEYCOM offers a complete line of millimeter wave lenses for microwave, millimeter wave and submillimeter wave applications upon your requests.

Our unique anti-reflection coating solves the problem of increased insertion loss due to reflection of radio waves on the lens surface and resonance due to multiple reflections.
