SOLA light engine®

Solid state white light excitation subsystems

Power and Control, 21st Century Illumination for 21st Century Microscopy

Lumencor offers a bright, solid state white light source as an alternative to traditional mercury arc lamps: the SOLA light engine.  The SOLA SM and SOLA SM 365 models operate via simple manual on/off control or with the aid of a foot pedal. SOLA SE and SE 365  light engines provide all the features and benefits of SOLA SM models with added capabilities for electronic control of both light output on/off status and intensity. SOLA light engines offer unprecedented access to solid state illumination at a price comparable to most metal halide light sources. While SOLA is very simple to operate, be assured it is also very powerful. Expect several watts of visible light pumped through the light guide, giving ample intensity for even the most demanding microscopy applications.  Integration of SOLA light engines with existing filter cubes and hardware configurations is straightforward. Cost of ownership is reduced relative to lamps because of long life time, no bulb or light guide replacements and energy efficient operation. The output spectral range is targeted for the VISIBLE spectrum, no deeper UV or IR is produced. Why would anyone use an arc lamp when a superior mercury-free alternative, SOLA, produces more light with less power, requires no maintenance, generates very little heat and is highly efficient in a compact design?

Customers will never again have to worry about arc lamp alignment, installation and replacement. The expected lifetime of the SOLA light engines is greater than 20,000 hours. Essentially no warm-up time and superior stability mean these are all usable hours with highly reproducible output power. Units ship with a warranty covering any failures with the light engine including parts and labor.
