The SCHOTT KL1500 compact cold light source is a new 150-watt halogen cold light source, developed and designed for applications in machine vision, stereo microscopy and macroscopy. With its modern and aesthetic design the typical "Look and Feel" of the KL family is maintained. Concentration onto basis features compared to the high-end LCD light sources allows an excellent price-performance-ratio. The KL 1500 compact cold light source is driven by an autoswitching wide range power supply which covers a range from 85 to 264 volts at 47 to 63 Hz for world wide usage. The high frequency (approx. 20 kHz) light source is digital camera proof - no flicker effect at short exposure times in "Life Image" mode. The KL 1500 compact has been approved and certified as laboratory and electromedical device by CSA (C/US) and is in compliance with the CE regulations.
