Surface Mat Styles
Array top surfaces come in two styles, Lens Mat and Diffuse Mat.



About Array Cooling and Base Options
Lumidox® II LED Arrays can generate a considerable amount of heat at any output stage and therefore need to be cooled. Both Lens Mat and Diffuse Mat style arrays are available with an Active Cooling base, Solid base or Flow-Through base. Each has it’s own specific way of cooling the LEDs in the array and can affect different application situations.




Note: All LED arrays can operate in an incubator at 37ºC, 95% humidity

For added protection, each device has a built-in thermal cutoff switch that, in case of overheating, will automatically shut down the unit. The trip temperature for Solid Base and Flow-thru Base Arrays is 95°C, and will reset when cooled to 65°C. Active Cooling Base Arrays will shut down if their temperature exceeds 75°C. They will reset once they have cooled to 45°C.

Note: Active Cooling Base arrays are not compatible with strong magnetic fields such as those found in most tumble stirrers due to interference with the cooling fans.

Lumidox® II STAGE Selection
By default, all Lumidox II devices are factory calibrated with 5 discrete linearly stepped output STAGES (Example 1, below). STAGE 1 output is the least radiometric power while STAGE 5 output is the most. For LED arrays with Active Cooling Stage bases, STAGE 5 thermal dissipation requirements are configured to an appropriate level for each device's built-in thermal satisfaction abilities. STAGE 5 defaults for Passive (solid) Base Arrays are tuned to be thermally satisfied with an average powered chiller in thermal contact with the array base. STAGES are calibrated to nearest whole number of radiant flux, and displayed in milliwatts (mW).

Analytical Sales & Services offers custom tuned stages to meet specific and unique requirements. A user, for example, may have a more sophisticated cooling mechanism and require an array tuned for maximum light output. In this scenario, Analytical would tune the upper STAGES to higher levels than typically thermally controllable by standard users (Example 2). In another example, a user may have a need for a tighter resolution of STAGES (Example 3).

For custom STAGE settings, please contact Analytical Sales & Services before ordering. Note: STAGES may only be calibrated at the time of shipment.
