These polished polyacrylate blocks are used to investigate multiple echoes and measure frequency-dependent attenuation. A 4 MHz transducer (U10017) is especially suitable for such measurements. An echo pattern comprising at least 3 echoes is recorded, and the spectra of the individual echoes analyzed. The result of the analysis is a shift in the average frequency […]

Equipment set for experiments on geometric and wave-mechanical acoustics. Based on the piezo-effect discovered by the Curie brothers, an AC voltage is applied to a piezo-electric body causing it to oscillate. Sound waves can also be used to excite the body and the oscillations can be converted into an electrical voltage signal. Resonant frequency:           40 kHz […]

Sample trough for CT scanner made of thin transparent plastic. Includes several special fittings for attaching and connecting ultrasonic sensors to the sides of the trough. Since transparent acrylic exhibits a very low acoustic impedance step response as compared to water, reflections are largely eliminated. Material:        Acrylic Thickness of sides: 4 mm approx. Dimensions: 430x150x150 […]

Model of the human eye, enlarged to a scale of 3 to 1, including the cornea, the lens and glass bodies for demonstrating the fundamentals of ultrasonic biometry. The biometric ratios in the human eye (distance between cornea and lens, thickness of lens, distance between lens and retina) are very well suited to demonstrating measurement […]

Made of transparent acrylic, with a lid and a transducer mounting for conducting the Debye-Sears experiment or projecting ultrasonic waves with divergent light. Three adjustment screws can be used to produce a stationary wave. A laser fixture with a lens mounting aligned vertically to the sound axis. Includes a plano-convex lens on a square mounting […]

Controller for operating the two stepper motors for the linear motion axis and the rotation axis of the CT scanner. Control of motion or direction of rotation, as well as linear speed and rotational velocity can be set manually or with a PC via a USB connection. Output:          2 x Stepper motor controllers, bipolar, 5 […]

CT scanner for turning and moving samples for the purpose of generating tomographic images. All turning and movement is carried out by means of stepper motors. While the measurement is taking place, the scanner moves the sample backwards and forwards between the ultrasonic sensors connected to the outside of the sample container in accordance with […]

  Våggenerator med kontinuerligt ultraljud för produktion av kontinuerliga och kraftfulla ultraljudsvågor i ett brett frekvensintervall upp till 20 MHz. Inkluderar en flerfrekvenssond med en formad, vattentät och ljudöverförande yta. Sändarfrekvensen kan justeras i digitala steg om 1 Hz och detta indikeras på en display. Den akustiska effekten kan också justeras genom att reglera sändarspänningen […]

Operativ enhet för utförande av ultraljudsexperiment i reflektionsläge (pulseko) eller utspädningsläge med ultraljudsgivare 1 MHz (1018617), 2 MHz (1018618) och 4 MHz (1018619). Med den inbyggda överförings- och mottagarenheten, ”time gain control” (TGC), integrerad analog-digital omvandlare och mikroprocessor för anslutning till mät- och utvärderingsdatorn via USB-gränssnittet. Anslutning av ultraljudsgivaren via robusta grenuttag med automatisk igenkänning […]

FlowDop 200, en dopplerapparat med ultraljud, genererar överföringssignaler med en justerbar frekvens på 1, 2, 4 eller 8 Mhz. Dessa signaler överförs med den anslutna sonden i form av ultraljudsvågor. Om dessa vågor reflekteras eller sprids av rörliga partiklar eller bubblor, då genomgår vågorna en frekvensförskjutning (dopplereffekt). De reflekterade eller spridda ultraljudsvågorna registreras och analyseras […]

Black plastic cylinder with non-uniform absorption and speed of sound within its interior. With magnetic holder for attachment to the revolving stage of the CT scanner. In the case of ultrasonic tomography, two different measurement variables can be recorded, absorption and speed of sound. Diameter:      60 mm Height:           70 mm
