BURLINGTON, Vt., Oct. 21, 2010 — A subsidiary of Chroma Technology Corp., 89 North has released the Heliophor, a pumped phosphor-based light engine designed for a wide range of quantitative fluorescence imaging applications. It features six user-exchangeable, high-intensity wavelength modules chosen from nine available. With advanced triggering and control capabilities, including the ability to upload macros, the light engine enables rapid, multidimensional imaging. It combines high output power, rapid switching times and submillisecond digital shuttering to enable high-speed, live-cell imaging. It has a liquid lightguide and flexible control architecture to quickly integrate into experimental setups. Its good stability and straightforward calibration system ensure consistent output intensity for every measurement taken. A limited lifetime warranty ensures stable, high-output power for reliable quantitative fluorescence for the life of the system. The device is an alternative to currently available light sources for fluorescence imaging including arc lamps, metal halides and LEDs. The company says that, compared with traditional arc lamps and metal halides, it has greater power and better long- and short-term stability. It also offers a longer lifetime and lower environmental impact. Digital control enables high-speed shuttering, whereas mechanical shutters must be used with traditional lamps. The company says that the light engine offers up to 20 times greater output power than LED-based light sources, and the high power output is present at wavelengths not supplied by light sources that use LEDs alone. Its high output power and digital shuttering make it possible for almost any laboratory to conduct experiments that were previously possible only in dedicated microscopy facilities. The digital shuttering enables running of fluorescent experiments without mechanical shutters and filter wheels. Along with flexibility in control architecture, the Heliophor’s physical components, including LED modules, optical filters and dichroics, are all user-interchangeable. These features minimize start-up times and expense, making it possible for labs without extensive engineering expertise to quickly and easily establish new experimental protocols.
