Speed of Light Meter Set
Article No: 11226-88
The complete set to measure the light velocity in air, transparent liquids and solids. Light speed and distance measurement with one device – state-of-the-art digital measurement technology makes it possible The device impresses with its simple design and minimal adjustment requirements The phase comparison method of a high-frequency modulated laser beam allows the speed of light in air to be measured with an accuracy of 2% Measurements can be performed with or without an oscilloscope The integrated display of all relevant measured variables (ƒ, Δφ, Δt, Δx) makes the device particularly attractive for practical work and demonstration experiments Modulation frequency: 50.0 MHz (quartz stabilised) Laser protection class: Class 2 according to DIN EN 60825-1 Digital display: 3-digit LED display Digit height: 20 mm Operating voltage: 12 VDC (suitable power supply unit 12 VDC/2.25 A, 12151-99 included in delivery) Power consumption: 5 W Scope of delivery: 1 x light velocity measuring apparatus 1 x retroreflector with stem 1 x power supply 12 V/ 2 A 1 x slide mount for optical bench 1 x optical bench, l = 1800 mm 1 x holder for speed of light measuring instrument 1 x acrylic glass cylinder with a holder, 1 x tubular cell with a holder 1 x USB data cable Dimensions (mm): 206 x 130 x 160 Weight: approx. 2 kg
