precisExcite®
Overview
precisExcite represents the very latest in fluorescence excitation. It uses LED Array Modules (LAMs) as a source of excitation. LEDs offer significant benefits over conventional lighting technology. The LEDs are actively-cooled to ensure the highest intensity and are extremely stable and long lasting. Both manual control and software operation are available. precisExcite is supported by many of the leading imaging software packages. precisExcite is a self-contained unit which is operational within a few minutes of unpacking.
The system comprises: a main unit which powers and cools the LED Array Modules (LAMs); a manual control pod; light-guides which connect the unit to a combining collimator which then fits directly onto the microscope; an adaptor which fits all current microscopes.

Modular configuration
Excitation of your fluorophores can be achieved by selecting the appropriate wavelength LAMs (LED Array Modules) from CoolLED’s constantly increasing range of available wavelengths. These are interchangeable depending on which fluorophores you wish to excite.
There are two configurations for precisExcite: Standard collimator and the pE-2 collimator. The Standard unit is suitable for most fluorescence applications and as a secondary light source for Confocal systems. The pE-2 configuration has a more sophisticated collimator which is particularly suitable for Live Cell imaging and fast-switching (~300 microsecond) applications.
