High-Frequency Single-Crystal Ophthalmic Imaging Transducer
The LNO-75 is a high-performance, single-element ultrasonic transducer engineered specifically for high-resolution ophthalmic imaging applications. Fabricated using a 36° Y-cut lithium niobate (LiNbO₃) single crystal, it operates at 75 MHz with an exceptionally wide bandwidth of 92%. Its press-focused design and optimized acoustic stack enable detailed visualization of anterior ocular structures, making it ideal for ultrasonic biomicroscopy (UBM), corneal imaging, and preclinical eye studies.
