About Oldelft Ultrasound

Oldelft was founded in 1939 as a company specialized in optics. In the 1980s, Oldelft started with the development of ultrasound transducers. These were the very early days of medical ultrasound probes. Oldelft introduced the first TEE (transesophageal echocardiography) transducers in 1988. Since then, the company has delivered many TEE transducers to all major ultrasound companies.

In 1998 Oldelft Ultrasound split off from the Oldelft mother company and started operating as a separate business unit within Delft Instruments.
