Scanning Acoustic Microscope II
Model: Tessonics AM 1103



Mechanical Scanner: Provides precise measurement and positioning of the acoustical lens in a volume 100x150x50 mm with repeatability not worse than 2 micrometer in the X and Y direction and not worse than 0.2 micrometer in the Z direction.

Acoustical transducer: Typically, the microscope is operating with spherically-focused transducers with nenter frequency in the range of 5 to 400 MHz. Note, however, that the system will also work with cylindrically focused transducers for anisotropy measurements and flat transducers for measurement in layered structures.

Pulser: Sending out spikes with amplitude 10-200V, repetition frequency, 0.1 – 10KHz and duration 3 – 50 ns.

Receiver: Gain not worse than 80 dB with the range 10 – 300 MHz. Analog to digital converter has an input bandwidth of 400 MHz and the equivalent conversion rate of 533 megasamples per second.

Controlling software: Manages function and interaction of units and provides acquisition, visualization, and analyzing of three-dimensional data. The software has a friendly user interface and provides full control over the system.

Electrical power: 120V AC (220V AC optionally)

Operating temprature: 10degree C top 30 degree C.
