New 3LS stroboscope
Cambridge Ultrasonics started internal trialing of its new 3-LS stroboscope in January 2011. It is hoped the product will go on sale in 2012. The high performance stroboscope is intended for research and industrial applications and will be competitively priced. It has three light sources, unlike most other stroboscopes with just one light colour. All light sources are advanced solid-state devices providing three different light colours in one unit: white (100 lumen incoherent), red (120 lumen incoherent) and an optional infra-red (25 W pulsed laser coherent). The 3-LS has a shortest light flash of 5 ns duration enabling it to freeze the motion of fast events. It also has digital synthesized timing control making it very accurate and stable in operation. It has three modes of operation. In the simplest mode only one switch is used to select the light source otherwise the 3LS strobe follows an external trigger signal. In the advanced mode of operation the 3-LS is controlled by a Windows program using a USB interface. In the third mode of operation, push-buttons and a small character display are used to control the 3LS through a simmple menu. The device is small, powered from 12 V DC and is intended for research and university teaching but can also be used in industrial applications.
