LN-300 | Ultra-High Frequency (UHF) Needle Transducer
The LN-300 is the highest-resolution transducer in the LN-Series, engineered for near-optical-level imaging performance. Operating at 275 MHz, this needle-type device achieves axial and lateral resolutions below 7 μm, enabling cellular and subcellular visualization in applications such as corneal epithelium imaging, zebrafish eye studies, and high-frequency ultrasound biomicroscopy.
