Article No: 11226-99
With the Speed of Light Meter you can measure the velocity of light in air and in other transparent media and additionally you can determine the distance. Measuring the speed of light, as well as distances, with only one device all thanks to state-of-the-art digital measuring technology The unit is convincing by a quick set-up and a need of minimum adjustment The speed of light can be measured with an accuracy in air of +/- 2% Measurements can be performed with or without an oscilloscope Due to the integrated display of all of the relevant measurement quantities (ƒ, Δφ, Δt, Δx) the unit is of special interest for student and teacher experiments Distance measurements can be performed with the same device Technical data and features Modulation frequency: 50.0 MHz (quartz stabilised) Protective class: Laser Class 2 acc. to DIN EN 60825-1 Digital display: 3-digit LED-Display Digit height: 20 mm Operating voltage: 12 V DC Power consumption: 5 W Housing dimensions: 206 mm x 130 mm x 160 mm Weight: approx. 2 kg Included accessories 12151-99 Power supply 12 V DC/ 2.25 A 11226-01 Retro-reflector with rod (1) 09822-00 Slide mount for optical bench Recommended accessories 11226-02 Optical bench l = 1800 mm for speed of light measurements 11226-03 Holder for speed of light meter 09822-00 Slide mount for optical bench (2) 11226-04 Acrylic glass cylinder with holder 11226-05 Tubular cell with holder
