Abstract
An optical microscope and method for detecting lens immersion in optical microscopy includes an ultrasound circuit acoustically coupled to both an objective lens and a sample of an optical microscope, the ultrasound circuit comprising an ultrasound transmitter and an ultrasound receiver. The optical microscope and method includes transmitting an ultrasound pulse from the ultrasound transmitter to the ultrasound receiver, determining that a transit time of the ultrasound pulse is less than a threshold time, and providing an output signal from the pulse discriminator indicating that the ultrasound pulse is less than the threshold time.
