Light Source
pE-300white
CoolLED's pE-300white offers intense, broad-spectrum LED illumination for imaging most common fluorescent stains. The pE-300white Light Source can be fitted directly to the microscope or specified with a liquid light guide. The system is a mercury-free alternative that is safer, more controllable, and repeatable than conventional high-pressure gas discharge illuminators. Spectral coverage is from the UV (DAPI excitation) to the Red region (Cy5 excitation). The system is perfect for hospital and regular research laboratory environments.

Light Meters
Light Meters are used to measure the light output of an illumination source for a number of optical applications. Light Meters are measurement devices that feature photodiodes to determine the level of light transmitted from a source. Light Meters possess simple, easy to read screens upon which measurements are displayed in one or more photometric units. Most Light Meters possess traceable NIST certification for proof of accuracy.
