Volpi USA has unveiled intraLED 3, a compact and economic LED light source. The system has a service life of 50,000 h and a light intensity of >500 lm, measured on a 1-m lightguide with an active diameter of 13.5 mm. It is intended for use in machine vision and industrial microscopy applications. With light homogeneity of ±5% and a typical color temperature of 6000 K, intensity adjustment is done either manually via the integrated RS-232 interface (optional USB) or via the multiport with digital and analog input. The intraLED 3 is available in two variations and is compatible with lightguides from Volpi and Schott-Fostec. Most applications with 100- or 150-W halogen light sources can now be implemented with an intraLED 3.
