TSI Microscope System 660000

TSI Microscope System 660000

The Model 660000 Inverted Microscope is a major component in TSI microPIV systems. When equipped with all the necessary accessories, the microscope allows the measurement of microchannel regions with sizes from µm to mm. The laser beam illumination is provided using an optical fiber with beam attenuation adjustment. An epi-fluorescent optic allows illumination and collection of fluorescent emission from the seed particles through the same optical path. Such an arrangement is essential to obtain particle images with high signal-to-noise level and, consequently, accurate velocity fields.

Patented techniques on illumination, image capture and data analysis are incorporated to provide the most optimal system for microPIV applications. The microscope can be connected using a laser light guide to allow laser light to be coupled for illumination from the laser.
